Detailed explanation-1: -Known as the front-end of the compiler, the analysis phase of the compiler reads the source program, divides it into core parts and then checks for lexical, grammar and syntax errors.
Detailed explanation-2: -1. Lexical Analysis: Lexical analysis or Lexical analyzer is the initial stage or phase of the compiler. This phase scans the source code and transforms the input program into a series of a token.
Detailed explanation-3: -In compilers, the frontend translates a computer programming source code into an intermediate representation, and the backend works with the intermediate representation to produce code in a computer output language. The backend usually optimizes to produce code that runs faster.
Detailed explanation-4: -Aspects of the front end include lexical analysis, syntax analysis, and semantic analysis.
Detailed explanation-5: -Explanation: The phase of the compiler next to the lexical analysis phase is also known as Parser. Syntax analysis or parser accepts the tokens produced by the lexical analysis and gives the parse tree in the output.
