Parsing is the phase of the compiler that checks whether the sequence of tokens generated by the scanner (lexical analyzer) follows the syntax rules of the programming language. The parser constructs a parse tree which is used to generate intermediate code or to perform semantic analysis. Code optimization is performed later in the compilation process, after the syntax is confirmed to be correct. The semantic analysis and code generation phases come after the parsing phase.
