C++ version in your textbook page 166 171. Your instructor will also give hints and examples in class and you should incorporate them into your code. The input for your code should be a text file containing a simple arithmetic expression using named variables, parentheses, and integers. The output should be to the screen and it should consist of a stream of pairs of identifiers and lexemes corresponding to the input. For example , if we input : (sum + 47)/total, the screen output would as shown in the console window below. I have included pictures from textbook pages

/* front.c a lexical analyzer system for simple arithmetic expressions */ #include #include /* Global declarations / /*Variables */ int charClass; char lexeme [100]; char nextChar; int lexLen; int token; int nextToken; FILE *in_fp, *fopen ()
