Programming language



A programming language is a formal language that contains a set of instructions that produce a variety of results. Programming languages are used in computational programming for the implementation of algorithms. intizarblogger.com

Most programming languages ​​contain computer instructions. There are programming machines that use a set of specific instructions instead of the usual programming languages. Since the early 1800's, programs have been used to guide the operation of machines such as jacquard looms, music boxes, and player pianos. [1] The programs of these machines (such as a player's piano scroll) did not produce different behaviors in response to different inputs or conditions.

Thousands of different programming languages ​​have been created, and more are being created each year. Many programming languages ​​are written in a mandatory format (i.e. as a sequence of execution processes) while other languages ​​use a declarative format (not the way to achieve the desired result). Programming language-Digital-marketing,

The definition of programming language is generally divided into two parts: syntax (form) and terminology (meaning). Some languages ​​are defined by a descriptive document (for example, the C programming language is interpreted by ISO standards) while other languages ​​(such as Perl) have an effect that is treated as a reference. Is. Yes, some languages ​​are both languages, the basic language of which is a standard definition and there is a general extension that applies to it.

Definitions

Programming language is a reference for writing programs, which are features of calculations or algorithms. [2] Some authors have limited the term "programming language" to languages ​​that can express any algorithm. [2] [3] These features often include:

Function and target

A computer programming language is a language used to write a computer program, including a computer that performs some kind of calculation [4] or algorithms and possibly external devices such as printers. Disks. Drives, robots, [5] etc. are controlled. For example, PostScript programs are often created by computer programs or other programs to control the display. In general, programming language can define counting on an object, possibly an abstract machine. It is generally accepted that a complete description of a programming language includes a description of the machine or processor for that language, possibly ideal. []] In most practical contexts, the programming language includes computers. As a result, programming languages ​​are usually described and studied this way. []] Programming languages ​​differ from natural languages ​​in that natural languages ​​are used only for communication between people. While programming languages ​​also allow humans to direct machines.

Abstractions

Programming languages ​​typically consist of descriptive data structures and gender summaries to control the flow of manipulation or execution. The practical need, which supports large-scale analysis in a programming language, is summarized in principle. []] This principle is sometimes developed as a suggestion to the programmer so that such abstractions can be used properly.

The power of expression

Theory classifies the language of mathematics through the computers they are capable of expressing. All touring languages ​​can apply the same set of algorithms. ANSI / ISOSQL 92 and Charity are examples of languages ​​that do not complete touring, yet are often called programming languages. [10] [11]

Markup languages, such as XML, HTML, or Turf, which describe structured data, are not generally considered programming languages. [12] [13] [14] Programming languages, however, may share syntax with markup languages ​​if any computational semantics is defined. Programming language-Digital-marketing, For example, XSLT is the complete language of Turing that uses XML syntax. [15] [16] [17] In addition, there is a complete touring subset of latex, which is mostly used to produce 

documents. 



The term computer language is sometimes replaced with programming language. [20] However, the use of both terms varies from author to author, including the exact scope of each. In one use, programming language is considered a subset of computer languages. [21] Similarly, languages ​​used in computing that have a different purpose than the expression of computer programs are usually designated computer languages. For example, markup languages ​​are sometimes referred to as computer language to emphasize that they are not intended for programming. [22]

Another use is called theoretical constructs and programming, abstracts in programming languages ​​for machines and their subclasses that run on physical computers, with limited hardware resources.  [23] John C. Reynolds emphasizes that formal explanatory languages ​​are as much the language of programming as the languages ​​of implementation. He also argues that textual and even graphical input formats that affect computer behavior are programming languages, despite the fact that they do not usually complete touring, and comment that Ignorance of programming language concepts is the cause of many errors in input formats. [24]

History

Main article: History of programming languages

Fast development

Very early computers, such as Colossus, were programmed without the help of a stored program by modifying their stock or setting up a physical control bank.

After a while, the programs could be written in machine language, where the programmer writes each instruction numerically so that the hardware can be executed directly. For example, the instruction to add value to two memory locations may include 3 numbers: an "opcode" that selects the "add" process, and two memory locations. Programs were read in decimal or binary format, with perforated cards, paper tape, magnetic tape, or toggles on the switch on the front panel of the computer. Machine languages ​​were later called first generation programming languages ​​ (1GL). intizarblogger.com

The next step was the development of the so-called Second Generation Programming Language (2GL) or assembly languages, which were still tied to specific computer instruction set architecture. They made the program more readable and saved the programmer from painful and inaccurate speech.

The first advanced programming languages, or third generation programming languages ​​(3GL), were written in 1950. The first high-level programming language for computers was Planck Cole, developed by Conrad Zeus for the German Z3 between 1943 and 1945. However, it was not until 1998 and 2000 that it was implemented. Programming language-Digital-marketing,

John Molly's short code, proposed in 1949, was one of the first high-level languages ​​developed for electronic computers. [26] Unlike machine code, short code statements represent mathematical expressions in an understandable form. However, each time the program was run, it had to be translated into machine code, which is much slower than running the equivalent machine code.

At the University of Manchester, Alec Galney developed auto code in the early 1950s. As a programming language, it is capable of automatically changing machine code. Developed a language. The first code and compilation was developed for the Mark 1 computer at the University of Manchester in 1952 and is considered the first language of modern programming. [27] [28]

R1 for the second auto code sign was developed by the broker in 1954 and is called "Mark 1 auto code". Brooker teamed up with the University of Manchester to develop an auto-code for Frontier Mercury in the 1950s. The EDSAC2 version was developed in 1961 by DF Hartley of the Cambridge University Mathematical Laboratory. Known as the EDSAC2 autocode, it was a direct development of the local adaptive mercury autocode and was designated for its object code optimization and source language. Assessments that were advanced for that time. A modern but separate development thread for the Manchester University Atlas 1 machine, Atlas AutoCode, was developed.

In 1954, Forten was invented by John Beck at IBM. Unlike just one design on paper, it was the first high-level general-purpose programming language used in practice. Programming language-Digital-marketing, It is still a popular language for high-performance computing, [1] and is used for programs that provide quality and status to the world's fastest supercomputers. 

Another language of early programming was developed in the United States by Grace Hooper, called FLOW-MATIC. It was developed for UNIVAC I in Remington Rand from 1955 to 1959. Hopper found that business data processing clients were anxious about mathematical cues, and in early 1955, he and his team wrote and implemented an authorship for the English programming language. A prototype [33] flowmetric compilation became publicly available in early 1958 and was widely

completed in 1959. Fluometric greatly influenced the design of COBOL, as at that time only he and his direct descendant Amako were used. . 

Payment

The growing use of high-level languages ​​requires low-level programming languages ​​or system programming languages. These languages, to varying degrees, provide facilities between assembly language and higher level languages. They can be used to perform tasks that require direct access to hardware facilities, but still provide a high level of control structure and error checking.

From the 1960s to the late 1970s, large samples of language were developed.

APL introduced array programming and influenced active programming. 

ALGOL's systematic approach improved both programming and language detail discipline. The "Revised Report on Algorithmic Language ALGOL 60" became an example of how language definitions were later written.

Lisp, enacted in 1958, was the first practical programming language to dynamically typed.

In the 1960's, Simula was the first language developed to support object-oriented programming. In the mid-1970s, Smaltalk developed the first "purely object" language.

C was developed as a system programming language for the Unix operating system between 1969 and 1973 and is still popular today. 

Prologue, designed in 1972, was the first logical programming language.

In 1978, ML developed a polymorphic typing system at the top of the LESP, which typed typing programming languages ​​permanently.

Each of these languages ​​formed a generation, and most modern programming languages ​​consider at least one of them to be their ancestor.

The 1960s and 1970s also saw a lot of debate over the merits of artificial programming, and whether programming languages ​​were designed to support it. In a famous letter published in ACM Communications in 1968, advocate Jacestra argued that Goto's statements should be removed from all "high-level" programming languages. [39]

Stability and development

A collection of textbooks that teach programming in both popular and obscure languages. These are just some of the thousands of programming languages ​​and dialects in history.

The 1980s was a year of relative stability. C ++ Common object based and system programming. The United States government has standardized a system programming language base, derived from Pass Cockle and used by defense contractors. In Japan and elsewhere, large sums of money have been spent researching so-called "fifth generation" languages, including the construction of logical programming.  [40] Language active groups to standardize ML and LESP. Moved. All of these movements explained the ideas invented over the decades, rather than inventing new parables.

One of the major trends in language design for large-scale system programming during the 1980s was the growing focus on the use of code modules or large-scale organizational units. Modula-2, Ada, and ML developed notable module systems in the 1980s that are often associated with general programming constructs.

The rapid development of the Internet in the mid-1990s created opportunities for new languages. Pearl, originally a Unix scripting tool first released in 1987, became popular on dynamic websites. Java was used for server-side programming, and with the promise of "Write Anywhere, Run Anywhere" (UCSD Pascal in the early 1980's) bike code virtual machines became popular again in commercial settings. Was famous). These developments were not primarily novel. Rather, they improved many existing languages ​​and patterns (although their syntax was often based on the C family of programming languages).

The evolution of programming language continues in both industry and research. Current guidelines include security and reliability validation, new types of modularity (maxins, delegates, aspects), and database integrations such as Microsoft's LinQ. Programming language-Digital-marketing, Fourth Generation Programming Languages ​​(4GL) are computer programming languages ​​that aim to allocate internal computer hardware details at a higher level than 3GL. Fifth Generation Programming Languages ​​(5GL) are programming languages ​​based on problem solving using program interventions rather than programmer's written algorithms.

Elements

All programming languages ​​have some basic building blocks (such as adding two numbers or selecting an item from a set) to define and implement or modify data. These ancient ones are

defined by grammatical and terminological principles that describe their structure and meaning, respectively.

Syntax intizarblogger.com

Main article: Syntax (programming languages)

Parser the Python code tree with Inset Tokenization

Syntax highlighting is often used to help programmers identify elements of source code. The language above is Python. The surface shape of a programming language is known as its syntax. Most programming languages ​​are purely textual. They use text layouts, such as words, numbers, and symbols, in written form, like natural languages. On the other hand, there are some programming languages ​​that are more graphical in nature, using visual connections between symbols to explain the program.

The syntax of a language describes the possible combination of symbols that produce artificially correct programs. Symbolic combinations are handled by the given meanings of words (strictly coded in compliance with formal or a reference). Because most languages are text-based, this article deals with text syntax.

The syntax of a programming language is usually described using regular expressions (for lexical structures) and back light forms (for grammatical structures). Here is a simple grammar based on Lisbon:

This grammar explains the following:

The expression is one atom or one list.

 An atom is neither a number nor a symbol.

Numbers are an unchanging sequence of one or more decimal digits, followed by an optional plus or minus sign.

A symbol is a letter followed by a letter of zero or more (excluding white space); And

A list is a matching pair of brackets with zero or more expressions.

An excellent example of a token sequence is given in this grammar: 12345, () and (a b c232 (1)).

Not all artificially correct programs are semantically correct. According to the principle of language, many artificially correct programs are ugly anyway. And (depending on the authenticity of the language description and implementation) may cause errors in translation or implementation. In some cases, such programs may display ambiguous behavior. Even when a program is well defined within a language, it may have a meaning that was not intended by the person who wrote it.

Using natural language as an example, it will not be possible to grammatically correct the meaning of a sentence or if the sentence is incorrect.

"Colorless green ideas sleep with anger." Grammatically well formed but not generally accepted meanings.

"John is single married." Grammatically well trained but expresses a sense which cannot be true.

If the type elevation is omitted on the first line, the program will generate an error on the undefined variable "p" during compilation. However, this program will still be artificially accurate because type declarations only provide semantic information.

The grammar required to define the programming language can be categorized according to its position in Chomsky's classification. The syntax of most programming languages ​​can be distinguished by type-2 grammar, meaning they are context-free grammars. [222] Some languages, including Perl and Lisp, have configurations that allow implementation during the analysis phase. Languages ​​that have a structure that allows the programmer to modify the analysis behavior make syntax analysis an undeniable problem, and generally blur the distinction between analysis and execution. [43] Unlike Lisp's macro system and Pearl's eggplant blocks, which may include normal counting, C-macros are merely string replacements and do not require code execution. [] 44] the words

This term refers to the meanings of languages, as opposed to their form (syntax).

Static words

The meanings of static words define restrictions on the correct writing structure that are difficult or impossible to express in standard grammatical formal forms. [2] For compiled languages, static terms basically consist of terms that can be checked at the time of compilation. Examples include checking that each identifier is announced before use (in a language that requires such a declaration) or that there are separate labels on the arm of the case statement. [] 45 Many important restrictions of this nature, such as checking is used in the appropriate context (such as not adding a number to the name of a function), or subroutine calls have the appropriate number and type of argument. Yes, they can be enforced by specifying the type in the logic called system. Other forms of static analysis, such as data flow analysis, can also be part of static words. Advanced programming languages ​​such as Java and C # are a special assignment of assignment analysis, Programming language-Digital-marketing, as part of a permanent imbalance, a form of data flow analysis.

Animated words

Main article: Programming language terminology

Once the data is explained, the machine must be instructed to work with the data. For example, words can describe the strategy by which values ​​are assessed, or the way the state of the structure is described. The dynamic words of a language (also known as compliance semantics) describe the different constructions of the language and how and when to program. There are many ways to describe execution. Natural language is often used to describe words used in practical language. A significant amount of scholarly research has gone into the formal terminology of programming languages, which has led to the formal implementation of words. The results of this field of research show a limited application to the design and implementation of programming languages ​​outside the academy.

Type system

Key topics: data type, type system, and type safety

A typing system describes how a programming language categorizes values ​​and expressions into categories, how it can combine those types, and how they communicate. The goal of the typing system is to identify errors in the correct language and verify a certain level of accuracy in programs written in that language. And it must be implemented. Any decisive type of system involves commercial cooperation: while it rejects many misguided programs, it can do something right, even prohibitive, despite unusual programs. To ignore this aspect, there are many, many languages ​​in which there are typewriters, usually untested species that can be used by programmers for a variety of operations that are not generally allowed. Is. Allows In most typed languages, the typing system is only used to type check programs, but eliminates the need to write multiple languages, usually functional, inferior types, programmer type interpretations. The systematic design and study of type systems is called type theory.

Typed vs. Typed languages


A language is typed if the description of each operation specifies the type of data to which the operation applies.  [] 46] For example, the data presented by "this text between references" is a string, and in many programming languages ​​there is no point in stringing numbers and it will not be processed. Configuring this program ("Static" type test) may detect an invalid option and it will be rejected by the compiler of the error message that compiled it, or it may detect when the program is running ("Dynamic" type check), which will result in a runtime discount. Many languages ​​allow a function to handle this exception in the name of the exception handler and, for example, always return "-1" as a result.

Common languages ​​are typical of one of the typed languages. These are often scripting or markup languages, such as REX or SGML, and contain only one type of data [suspicious discussion] - usually character strings that represent symbols and numbers. Statistics are used for both.

In contrast, a non-typed language, like most assembly languages, allows any type of operation to be performed on any data, usually in pieces of different lengths.  [] Advanced] Advanced non-typed languages ​​include certain types of BCPL, TCL, and Fort.

In practice, while some languages ​​are considered for typing through typing theory (confirmation or denial of all functions), most modern languages ​​offer a degree in typing.  []] 46] Many production languages ​​provide means of ignoring or malfunctioning the type system in order to better control the program process.

Static vs. Dynamic typing

In static typing, all kinds of impressions are fixed, usually at the appointed time, before the program is implemented. For example, 1 and (2 + 2) are numerical expressions. They cannot be delivered to a function that is expected to be wired, or stored in a variable that is defined to hold history. [] 46]

According to statistics, typed languages ​​can be typed either explicitly or individually. In the first case, the programmer should clearly write the types of certain phrases (such as declaring a variable). Otherwise, the format evaluates the types of expressions and declarations based on the context. Most mainstream authentic typed languages, such as C ++, C # and Java, are clearly typed. The full assessment is traditionally associated with less mainstream languages, such as Haskell and ML. However, many explicitly typed languages ​​support partial additions. For example, C ++, Java, and C # In some limited cases, all kinds of infrared types. [47] Furthermore, some programming languages ​​allow certain types to be automatically converted to other types. For example, an intent may be used where program preparation is expected.

Dynamic typing, also known as latent typing, determines the security of the type of operations when executed. In other words, types are associated with runtime values ​​rather than textual expression. [] 46] Unlike typed infrared languages, dynamically typed languages ​​do not require the programmer to write clear interpretations of expressions. Among other things, this program may allow a variable to refer to different types of values ​​in different locations. However, such errors cannot be detected automatically unless a piece of code is actually executed, which may make debugging more difficult. Lisp, Smaltalk, Pearl, Python, JavaScript and Ruby are all examples of dynamically typed languages.

Weak and strong typing

Poor typing allows one type of value to be understood as another type, for example string number. [46] It can be useful at times, but it can also detect some types of program errors at set times and at runtime.

Strict typing prevents errors in these programs. There is an error trying to operate on the wrong type of value. [] 46] Strictly typed languages ​​are often considered type safe.

Alternative definitions of "weakly typed" refer to languages, such as Perl and JavaScript, which allow a large number of conflicting types of conversions. In JavaScript, for example, the expression 2 * x explicitly converts X to a number, and this conversion is successful even if the X is a column, undefined, a line or a string of characters. Programming language-Digital-marketing, Be Such implicit conversions are often useful, but they can mask programming errors. Strong and stable are now generally considered orthogonal concepts, but the use in the literature is different. Some use the term strongly typed to mean firmly, statically typed, or even more vaguely, which simply means static typed. Thus C is said to be both rigidly typed and weakly, statically typed. [48] ​​[49]

It may seem strange to some professional programmers that C can be called a "weak, stable type". Note, however, that the use of the normal pointer, the invalid * pointer, allows the pointer to be cast, without the need to explicitly cast on other pointers as well. It is equivalent to casting any type of data type as a row of bytes on a particular type of data type, such as (cast) or (four).

Standard library and runtime system

Main article: Standard library

Most programming languages ​​have an associated basic library (sometimes called a 'standard library', especially if it is included as part of a published language standard), which is traditionally a language Available through all implementations. Basic libraries include commonly used algorithms, data structures, and definitions of input and output methods.

The line between a language and its basic library varies from language to language. In some cases, language designers may view the library as a separate entity from the language. However, the basic language library is often perceived by its users as part of the language, and some language definitions also require that this library be made available in all implementations. In fact, some languages ​​have been developed because the meaning of certain grammatical constructions cannot be explained without reference to the basic library. For example, in Java, the literal part of the string is given as an example of the java.lang.String class. Similarly, in Smaltalk, an anonymous function express ("block") generates an example of a library's block context class. In contrast, the scheme has several integrated subdomains to develop the rest of the language as library macros. Are therefore sufficient, and therefore language designers do not even say which parts of the language should be applied as language formation, and which should be partially applied to a library. intizarblogger.com

Design and implementation

Programming languages ​​share features related to natural languages ​​for their purposes, such as vehicles for communication, a grammatical form of which differs from its words, and branches of related language families to each other. ۔ [] 0] [] 1] But as an artificial structure, they also differ from the language in the basic ways that have been developed through use. One important difference is that a programming language can be fully described and studied in its entirety because it has a definite and limited definition. [2] In contrast, natural languages ​​change the meanings given to them by their users in different communities. Although constructed languages ​​are also artificial languages ​​that have been created from the ground up for a specific purpose, they lack the exact and complete semantic definition that a programming language has.

Details

Main article: Programming language details

Programming Language Description is a pattern that language users and implementers can use to agree on whether a piece of source code in a language is a valid program, and if so, how. ۔

 What will happen?

Programming language descriptions can take many forms, including the following:

Clear definition of language syntax, stable words and action words. Although syntax is usually defined by a formal grammar, word definition can be written in natural language (such as C language), or in a formal word (such as standard ML [57] and scheme [58] definitions). Is. ) Can be written in

Description of language translator behavior (e.g., C ++ and Fortune definitions) Language syntax and word definition should be judged in such a way that it can be written in natural or formal language.

Implementation of a reference or model, sometimes written in a particular language (e.g., prologue or ANSI Rex X []]]. ۔

Implementation

Main article: Implementing a programming language

Implementing a programming language provides a way to write programs in this language and follow one or more configurations of hardware and software. There are two broad approaches to implementing programming languages: compilation and interpretation. It is usually possible to implement a language using any technique.

A set can be created by hardware or by a program called interpreter. In some implementations that use the translator's point of view, there is no specific boundary between the compiler and the translator. For example, set some BASIC implementations and then execute one line at a time on the source. intizarblogger.com

Programs found directly on the hardware usually run much faster than those described in the software. [60] [Need better resources] Programming language-Digital-marketing, One technique to improve the performance of the programs described is to set up only temporarily. Here the virtual machine, just before the execution, translates the blocks of motorcycle code that are to be used in the machine code to perform the hardware directly.

Proprietary languages

Although the most commonly used programming languages ​​are fully defined and implemented, many programming languages ​​exist as proprietary programming languages ​​with only one vendor available who can claim that such Proprietary language is their intellectual property. Proprietary programming languages ​​are usually domain specific languages ​​or internal scripting languages ​​for a single product. Some proprietary languages ​​are used only internally within the seller, while others are available to external customers.

 

Some programming languages ​​are on the border between proprietary and open. For example, Oracle Corporation claims ownership of certain aspects of the Java programming language, [1] and Microsoft's C # programming language, which applies to most parts of the system, is also common as a closed environment. ۔ Language is runtime (CLR). [62]

Many proprietary languages, despite their proprietary nature, are widely used. Examples include MetLab, VBS Script, and WolfGram language. Some languages ​​can move from closed to open. Earring, for example, was originally Ericsson's internal programming language. [] 63]

Use

Thousands of different programming languages ​​were created primarily in the computing field. [[] 64] Individual software projects typically use five programming languages ​​or more. [] 65]

Programming languages ​​differ from other forms of human expression in that they require more precision and completeness. When using natural language to communicate with other people. When they do, human writers and speakers can get confused and make even small mistakes, and still expect to understand their intentions. Symbolically, however, computers "do exactly what they are told to do," and the programmer cannot "understand" the code he wants to write. The combination of language definition, a program, and program input must fully explain the behavior that occurs in the domain of program control when the program is executed. On the other hand, ideas about algorithms can be communicated to humans without the need for health-related requirements that need to be implemented through a supplemental code that translates to natural language with code written in a programming language.

Measurement of language use

Main article: Measuring the popularity of programming language

It is difficult to determine the commonly used programming language because the definition of usage has context. A language programmer can capture a maximum of hours, have more code lines in a different language, and use up a third more CPU time. Some languages ​​are very popular for special applications. For example, COBOL is still strong in corporate data centers, often on large mainframes. [[] 68] []] 69] Fortran in the use of science and engineering; Base in aerospace, transportation, military, real-time and embedded applications. And embedded applications and operating systems. Other languages ​​regularly write a number of applications.

Different methods of measuring language popularity, under different biases on each measurement, are suggested:

Counting job advertisements that mention language [70]

Number of books sold that teach or explain the language [711 7]

Estimate the number of existing lines of code written in a language - which can underestimate the languages ​​that are not often found in public searches. [] 2]

The number of language references (ie the name of the language) is found using a web search engine.

Collecting information from a number of Internet sites, Stockify.com listed the average ten most popular programming languages ​​(in descending order of overall popularity): Java, C, C ++, Python, C #, JavaScript. ۔ , VB, .NET, R, PHP, and MetLab. [] 73]

Speech, taste and work

The dialect of a programming language or data exchange language is a (relatively small) variation or extension of a language that does not change its nature. With languages ​​like Scheme and Fort, standards may be considered inadequate, inadequate, or invalid by enforcers, so they often deviate from the standard by creating a new bid. In other cases, the bid can be used in a specific language related to the domain, often a subset. In the Lisp world, most languages ​​that use basic S-impressions and words like Lisp are considered lease lectures, although they are as different as, say, racquets and classes. Because it is common to have multiple dialects in one language, it can be very difficult for an inexperienced programmer to find the right documents. There are multiple dialects in the basic programming language.

The explosion of the fourth bid resulted in "If you've seen a castle ... you've seen a castle."

Products

More information: Classic list of programming languages

There are no plans to categorize programming languages. The given programming language is not usually a unit language. Languages ​​are usually created by combining elements of many existing languages ​​with new ideas. Ideas born in one language can spread to families of related languages, and then family differences will be eliminated in a good family way so that they appear in a completely different family.

This task is further complicated by the fact that languages ​​can be classified from multiple axes. For example, Java is both an object-oriented language (because it encourages object-oriented organization) and a simultaneous language (because it has an internal structure to run multiple threads in parallel). Python is an object based scripting language. Largely, programming languages ​​are divided into programming patterns and categorized by the domain used, with the general purpose programming languages ​​distinguishing domain-specific programming languages. Traditionally, programming languages ​​are used to describe the number of essential sentences, that is, to issue commands. These are usually called mandatory programming languages. A great deal of research in programming languages ​​aims to blur the distinction between a program that describes a program about the set of instructions and the desired response, a key feature of declaration programming. [Programming language-Digital-marketing,] 74] Includes image programs, object-oriented programming, functional programming, and logic programming. Some languages ​​are patterned or multidimensional hybrids. Assembly language is not an example as a direct model of basic language architecture. Depending on the purpose, programming languages ​​can be defined as general purpose, system programming languages, script languages, domain specific languages, or synchronized / distributed languages ​​(or a combination of them). [] 75] Some common languages ​​were developed with large-scale educational goals. [76]
