I've never touched C++ but I have done a little C.
Is there any reason why you're using them headers?
You should only need stdio, like so


#include <stdio.h>

int main(void)
{
printf("hello, world\n");
return 0;
}

unless you were planning to expand. Were you trying to get stdin from the user? I'm Perl/Haskell guy. Sorry I can't be of more help
