    I don't know error
    Neither do we. If youre getting an error, tell us what and where the error is. There are many things wrong with your code, but we dont know which one youre referring to. We (or at least I) arent going to re-write your code either.

    Also, theres little point posting your code in "CODE" tags if you arent going to indent it. Lack of indentation adds just one more thing to this thread that will annoy people, therefore resulting in either no help or (seemingly) disrespectful or rude comments. "Help us help you".

    One more thing, this is C, not C++.
