newbie in c++

ok, well I feel completely retarted. I am doing a c++ tutorial and the very first program there is in this tutorial is the infamous hello world! I typed it out, saved it as a .cpp file, then I compiled it in g++. my question is how do I run it? I have no idea why I cant run it. oh here is the source for it

Code:

// my first program in C++

#include <iostream.h>

int main ()
{
  cout << "Hello World!";
  return 0;
}

I dont think that I have felt so retarted before.

Okay if its compiled you should now have a new program in the directory, to compile it simply type

./programname

You need the ./ since the current directory isn't allowed to execute programs ( security problems if you do ).

The program isn't 100% accurate for c++

Code:

#include <iostream>
using namespace std;

Would be better, I'm really just being picky, as both ways are legal c++, but what I've typed is more standard compilant, which is usually a good habit to get into.
