    And what, exactly, do you expect to be output? There is nothing in your code to perform such output - and you got the code-tags the wrong way around the one with the slash should be at the end.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    Where do you actually populate str?

    And I don't think that's the correct call of sprintf(), but I'm unsure from memory.

    My bad guys. I found the problem. Wasnt supposed to be a string, jus a char. I have it now.

    It's not supposed to be a char.
    A string is an array of chars. You've got a buffer overrun if you've defined str as merely a char.

    Maybe "%d" instead of "%s" would help?
