C++ Lex using CSharp is a system software ( Lexical Analyzer) project where the input program is broken down into many fragments called tokens. Basically lexical analysis involves scanning the program to be compiled and recognizing the tokens that make up the source statements. Scanners are usually designed to recognize keywords, operators, and identifiers, as well as integers, floating point numbers, character strings, and other similar items that are written as part of source program. The exact set of tokens to be recognized depends upon the ....etc
