Hi kitekeeter! This is a problem for a lot of noobies! What happens is when you start a program, it calls the starting function (main()). When it does this it processes what you tell it to process (in your case, you send Hello World to the console). After it's done processing, it ends the function and once the main() function ends, the application itself ends.

In other words, you need to somehow stop the function from ending to fast. A popular way is to place a function that uses an interrupt in the function. A popular choice is the C STD, getchar();

#include <iostream>

int main(int argc, char ** argv)
{
    std::cout << "Hello world! Nice weather, eh?" << std::endl;
    std::cout << "Press any key to continue...";
    getchar();
}

This is my personal way of doing it. There's a tutorial on this site explaining how and why this works.

I would only quibble with the phrasing of line 6 -- after all, any key doesn't work, just Enter. Hence:

6 std::cout << "Press ENTER to continue...";

Hope this helps.
