win32 console application.

i created the hello world test application, it makes this code

Code:

---

// test4.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

int main(int argc, char* argv[])
{
        printf("Hello World!\n");
        return 0;
}

---

but how do i actually run it and see the output hello world?

You select Project->Build from the menu.

On a side note, you created a non-empty project - this is bad for beginners. Create an empty project and make sure you actually include the correct headers: <stdlib.h> in your case, but that's only because you've written the C-style HelloWorld, not the C++ style as you should (the source file ends in .cpp, which means it's C++.)
