How do compilers work

  • What is compiler and how it works in operating system?

    In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language)..

  • The online compilers are webpages where you write your code and these codes are sent to the server which has the compiler built.
    The result is obtained as a response and rendered on the client-side again.

What are the different phases of a compiler?

A compiler is a computer program that transforms source code written in a high-level programming language into a lower level language.
Basically, a compiler consists the following phases:

  • Lexical Analysis
  • Syntax Analysis
  • Semantic Analysis
  • IR Generation
  • IR Optimization
  • Code Generation
  • Optimization.

    • What is the purpose of a compiler?

    A compiler is a program that translates human-readable source code into computer-executable machine code.
    To do this successfully, the human-readable code must comply with the syntax rules of whichever programming language it is written in.
    The compiler is only a program and cannot fix your code for you.
