Program Plan Intro

Lexical Analysis:

  • Lexical analysis converts high-level input program into a series of tokens and it also called as scanner.
  • It is implemented with the Deterministic Finite Automata (DFA).
  • A series of tokens are the output which is sent to the parser for syntax analysis.

Syntax Analysis:

  • The second phase of compilation is syntax analysis or parse tree.
  • It is used to check the given input is in the correct syntax format or not.

Semantic Analysis:

  • It ensures that statements and declarations of program are semantically correct.
  • Semantic analysis tests whether the built parse tree meets language rules.

Intermediate Code Generation:

  • It is used to translate the source code into the machine code.
  • In between the high-level language and the machine language, the intermediate code is translated.
