For Berkeley Yacc: http://rpms.mandrivaclub.com/search....arch+...&arch=
For GNU Flex: http://rpms.mandrivaclub.com/search....arch+...&arch=

(GNU Flex is a free lex.)

We cannot do your school work for you. The amount of knowledge you gain by doing it yourself will be well worth it; if you have someone else do it for you, you will learn nothing. Surely you have been specified a text book, and the internet contains a plethora of information that will help. I'm sure you'll be alright if you work hard and use properly the tools at your disposal.

hi taylor,

U are absolutely right and i agree with you. But the fact is that I dont have time to explore this stuff as I have my university final exams approaching soon. And I have been allotted this project with just 30 more days to go. I do not need whole solution. I just need few ideas, so that more innovative and create ideas sprout in my mind. I know that you all are experts at this field.

However, if you feel that I am still on the wrong path, never mind. If u think so, plz don't help buddy. I had many expectations and that y i posted this thread. Lemme clear once again, I do not need full solution of my project.

I hope u understand. In case i sound rude, plz don't misunderstand me.

I would welcome suggestions. Thank you
