You forgot to ask a question. Your debug output appears perfectly correct. Your output appeared in your program's console, but when your program ended, so did its console. — David Schwartz, May 19 '12 at 07:04
@Cicada: MS Visual C++ accepts `void` as the return type of the `main` function. — Mohammad Dehghan, May 19 '12 at 07:23
@MD.Unicorn That's not standard, it's a Microsoft Extension. — user703016, May 19 '12 at 07:28
Hence the `visual-c++` tag, I guess. In any case, that's one of Microsoft's _lesser_ crimes against the standard :-) — paxdiablo, May 19 '12 at 07:30

#include <iostream>
using namespace std
int main() {
    cout << "Hello World";
    cin.get();
    return 0;
}

This should work. The console exits before you can view the program. Using cin.get() will keep the program running until you press enter.

On a related note, your main() function really should be int and not void. I'm pretty sure some compilers do not allow void main().

That's because your console closes before you can see the output.

Try stepping through your program with F10. Or place a locking statement before the return.

Also, not that main should return int.

Try this:

#include <iostream>
using namespace std;
void main()
{
    cout <<"its my programm";
    cin.get();
}

Then you must hit the Enter to close the console window.
