Hi! Can someone tell me basic (if there is one) difference beetwen yacc and
bison? I mean, are they the same only bison is a better version, do they use
same input files?

Bison is the GNU version of yacc (yacc predates GNU, and there are no
doubt other yaccs). Bison does more than yacc, but should be upwardly
compatible with files input files designed for yacc.

On my GNU/Linux system /usr/bin/yacc is just a wrapper for bison anyway:

#! /bin/sh
exec /usr/bin/bison -y "$@"

The GNU version of lex is called flex and is the same idea-- lex is just
a wrapper for flex.

Good luck with your parser!
