![]() ![]() The Flex specification is processed as follows (the file lex.yy.c is produced): flex vars.l The YACC specification is processed as follows (files y.tab.h, needed by the Flex-generated code, and y.tab.c): yacc -dtv vars.y Compiling the C/C++ code (it is C++ simply because we programmed the extra code in that language): See, someone who is unemployed and have no kids, like a fresh grad, can easily grind out more compared to someone who is full time with kids. YACC is known as Yet Another Compiler Compiler. The following input file summarizes the form of the equations to be solved: unknown term = expression 11 x = 44 y = (2 + 4 * x) y abc = 18 4 z123 = (9 * x - 4 * abc) Call the compiler and input lex.c to it (eg: "tcc lex.c", where tcc is the Turbo C compiler use any C/C++ compiler you have). 1 lex and yacc lex amp yacc 2nd edition book.
