Definition of Compiler Programming Language

Rancakmedia.com - In the following we will provide an explanation of compiler programming language which you may not know. Come on, see more in the next article.

Certain coding frameworks support website creation. Then, how is the code converted into a website that can operate properly? The compiler is the instrument the programmer uses to convert it.

How does the compiler change the generated code so that it can be interpreted by the computer? What types of compilers are available for programmers?

Definition of Compiler Programming Language

A compiler is a program that converts natural language processing code into a form that computers can understand.

Technopedia shows that this conversion process compiles. In this step, the compiler runs code that tells the CPU's arithmetic logic unit when to use the high and low binary signals.

Definition of Compiler Programming Language

Web developers often use one of two types of compilers. A cross compiler that runs on machine 'A' and generates code for another computer, “B”. This compiler is capable of generating code for multiple platforms in addition to the platform it runs on.

A source-to-source compiler, sometimes called a transcompiler, is a compiler that converts source code written in one programming language into source code in another programming language. Although the main job of the compiler is to change the code.

There was a variety of additional work that was also completed. Here are some of them:

  1. Breaking the original program into parts and applying grammatical structures to them.
  2. Build the required target program from the intermediate representation and create a symbol table.
  3. It checks for deficiencies in the source code before compiling.
  4. Manage storage space of all variables and code.
  5. Support for multiple compilations is provided.
  6. Analyze the full program and translate its semantic equivalent after you've finished reading it.
  7. Depending on the system, convert source code to object code.

Language Processing System Steps

Before you can fully understand a compiler, you need to know how a language is interpreted by hardware.

  1. Hardware can understand a programming language called a high-level programming language (HLL).
  2. Programs that use # define or # include directives, such as # include or # define, are subject to the HLL standard.
  3. HLL tends to be closer to human language but still challenging for robots to understand.
  4. Thus, programs in these languages need to go through a series of modifications to make them machine friendly.
  5. That's where the computer's ability to understand language comes in.

Language Processing System Steps

Here are the steps mentioned:

Pre-processor

The compiler will add a file named file inclusion to the preprocessor run to omit any code that has the #include directive.

The extended macro will also be used to replace any code that currently uses the #define directive. Macro processing, augmentation, language extensions and so on are part of this process.

Assembler language is the final product of the compiler process. This language is not in binary or HLL format. This language is an intermediary that combines machine instructions and some additional important data needed for the next step.

Assemblers

Assembler is available for all platforms. Unfortunately, each hardware and operating system has a separate assembler. The assembler converts code in assembly language into machine understandable language.

The assembler output is referred to as an object file, which is a mix of machine instructions and the data needed to store these instructions in memory.

interpreter

The interpreter converts the HLL into machine readable language. Unlike a compiler, an interpreter interprets a program one statement at a time. As a result, compared to a compiler, an interpreter takes longer.

Relocatable Machine Code

Moveable machine code can be executed at any time. The addresses in the program will be created to match the way the program works.

Linkers

The linker helps you in combining multiple object files to create an executable file.

Each of these files can be generated using a different assembler. The main task of the linker is to find the module called by the program and the place in memory where all the modules are stored.

Compiler Programming Language Examples

Here is an example of the compiler, namely:

C++ Compiler Programming Language

C++ is a programming language that originates from the development of the C language created by Dennis Ritchie. C++ is often referred to as an object-oriented procedural programming language. C++ is often used by developers to create games, software, and so on.

Fortran Compiler Programming Language

Fortran is an acronym for formula translation, and is a programming language capable of handling sophisticated numerical computations. However, due to the high level of the language used, the Fortran source code is difficult to decipher.

Pascal Compiler Programming Language

Pascal is a programming language written using English structural algorithms, both imperative and procedural. Pascal is a programming language that provides effective programming structures and methods. One of the good things about Pascal is that it is written in a simple language that humans might understand more easily.

Visual Basic Compiler Programming Language

Visual Basic, or VB, is an uncommon programming language and can be called sophisticated because VB has the benefit of being able to easily build applications on the Windows operating system. VB is built with an integrated development environment that can make code easier to understand and fix or add to it.

Compiler Programming Language Phases

Following are the two main stages that the compiler process goes through.

Compiler Programming Language Phases

Analysis Phase

The following source code is used to build the intermediate during the representation step.

  1. The program is divided into "tokens" using a lexical analyzer.
  2. The syntax analyzer is a function that detects "sentences" in programs that use language syntax.
  3. The semantic analyzer is in charge of verifying the static semantics of each construct.
  4. Intermediate code generator, that is, the generator creates “abstract” code.

Synthesis Phase

When starting the synthesis phase, the analog target program is built from the intermediate representations. There are two elements in this phase.

  1. Responsible for improving the intermediate code generator code in the code to make it more efficient.
  2. Code generator, which converts code from an intermediate code generator into specific machine instructions.

Advantages of Using the Compiler is an important part of the code to ensure that the program executes correctly.

In addition, you may receive the following benefits when using the compiler.

  1. The compiler validates the entire program, so there are no syntax or semantic issues.
  2. The executable file is optimized by the compiler, so it runs faster.
  3. This allows you to build internal structures in memory.
  4. You don't need to run the program on the same system it was created on.
  5. You can convert the complete program into other languages.
  6. Can create files on disk.
  7. Link files into executable format.
  8. Check for syntax and data type issues.
  9. It helps you improve your understanding of language semantics.
  10. Help with problems related to one's ability to communicate effectively in another language.
  11. The approach used to develop the compiler can be used for other projects.

Difference between Compiler and Interpreter Programming Languages

The following are the differences between compiler and interpreter, namely:

Difference between Compiler and Interpreter Programming Languages

Definition

A compiler is a computer program that can translate computer programs produced in certain programming languages into other programming languages. An interpreter, on the other hand, is a program that can translate high-level instructions into simpler instructions.

Command

All instructions in the compiler can be evaluated at once, and the test procedure takes longer. However, because the commands in the interpreter are translated line by line, the test procedure is faster and the program can be tested immediately, despite the fact that programming language typing errors still occur.

Linkers

The compiler needs a linker to combine the object code with other libraries to produce machine executable code. While object code can be combined without the need for a linker by the interpreter,

Program Code

Since the program is executed as machine code by the compiler, the program code remains hidden. Programming languages that use compilers include Visual Basic, Fortran, Cobol, Pascal, and C. Code cannot be hidden in the interpreter, but the languages used are PHP, ASP, and Perl.

FAQs

Below we have summarized some frequently asked questions about compiler programming languages, as follows:

How Does Compiler Work?

The compiler process reads a source code in text form, combines related characters into a token, then checks whether the token meets the grammar, after which the compiler will check the input semantics, and also to make output in a language (which is generally assembly).

Conclusion

Well it's a programming language compiler that converts natural language processing code into a form that computers can understand. Compilers are capable of generating code for multiple platforms other than the platform on which the code is executed.

They can be cross compilers or source-to-source compilers. Macro processing, augmentation, language extensions and so on are part of this process.
