By doing lexical analysis, lex convert lexemes to tokens. In your source code for lex, you can create your keywords, definition range of variables and such that. Flex is using for lex. Flex which is a tool for generating scanners recognizes lexical patterns in text and convert source code to readable c code. Yacc is using with bison. By doing syntax analysis, yacc generate a compiler for the lex code. yacc’s source code is converted to c code includes header file. After all the operations, generated codes compile with gcc and then C-Based own programming language created.
