Description: Manually construct a C language to identify all the typical words such as: identifiers, numbers, operators, and if, while the determination of reserved words such as finite automata, and write on the procedure should be automatic machine then a simplified C language program for the input file, through the design of automata based on the lexical analysis procedure for obtaining the input file and within each code word table, and save the results to file the form (that is, TOKEN sequence). Defining themselves in all the regular expression into NFA, and then consolidated for the NFA ' , then NFA' into a DFA, DFA then converted to a minimum state DFA ' , the last by the DFA' into a lexical analysis program.
