CSC362.L01, Lab 4: Lex

Admin:
* No introductory statements; Do the lab

Topics:
* lex/flex

Notes:
* Be careful about .*, since that will match your complete input.
* printf("%s", yytext) is better than printf(yytext)
* printf("WHATEVER[%s]\n", yytext); is even better
* See silly.yy for an example of how to use flex to return values to another procedure.
