C++ Console app, Hello World! Problem

Im just starting C++ but i have got stuck straight away!

I have:

#include <iostream>
using namespace std;

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


It works fine, but just as it appears, it closes..and in the tutorial it shows the console with: 'press any key to continue...' under 'Hello World!'. Please Help!

cin.get();
