    > copy n' paste, so i cant do the code]....[code]
    Sure you can - just add them in manually afterwards.
    You just managed to type in 11 of the required 13 characters after all

    A woeful lack of ; at the end of way too many lines seems to be the biggest problem
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Contrast with your previous effort which had too many ;

    You've been given what you did wrong. You need ';' after statements. Without that, you can't compile. Also change void main() to int main().

    Without the program compiling, what kind of answer do you want to "can u guys actually tell me where i am wrong?"
