Introduction to Compiler

  • A compiler is a translator that converts the high-level language into the machine language.
  • High-level language is written by a developer and machine language can be understood by the processor.
  • Compiler is used to show errors to the programmer.
  • The main purpose of compiler is to change the code written in one language without changing the meaning of the program.
  • When you execute a program which is written in HLL programming language then it executes into two parts.
  • In the first part, the source program compiled and translated into the object program (low level language).
  • In the second part, object program translated into the target program through the assembler.
