A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar.
Implementation of the lexical, syntax and semantic analysis stages of a typical C/C++ compiler. The program is able to read a sample C/C++ code and process and analyze the source file to find errors in it. A graphical display shows the complete details of each individual stage of the compilation process comprehensively.
