Here you will get program to implement lexical analyzer in C++ Compiler is responsible for converting high level language in machine language. There are several phases involved in this and lexical analysis is the first phase.
Lexical analyzer reads the characters from source code and convert it into tokens.

After lexical analysis a symbol table is generated as given below.
Token Type c identifier = operator a identifier
- operator b identifier ; separator
