Hi.
could anyone please help me.
i am stuck at this moment.
doing my c programming assignment.
things are not working properly.
am i just a dummy?
please look at my code.
i will post it below.
i do not want people to do the assignment, just give me pointers on how to
fix the problems i have with my code.
