    Just make sure you never type "void main" please. Use "int main" if you see any sites using "void main". Just because the sites use it in their examples doesn't mean it's a good thing.

    Outside of your DOS world, your header file is meaningless.

    Is this some kind of standard reply that you just post if you don't have anything useful to say to a thread's topic ?

    No, but seeing as so many tutorials or stuff use void main, it can be good info.

    ....i copy and paste...
    Many tutorials dont give the "complete" code,for example if they want to teach you loops,they will just write:
    Code:
    for(i=0;i<10;i++)
    {
              i+=1;
    }
    If you copy-paste these kind of things,obviously you will get errors.So include all the necessary header files,and paste the code in int main()
