What to do with code?

Question

So I just started programming, and the first app I made is supposed to print 'Hello World!' on my screen. So I copied the code

#include  <iostream>
int main()
{
    std:: cout << "Hello World!" << std:: endl;
    return 0;
}

But now I'm wondering: Where can I see it? Where can I see 'Hello World!' being printed on a screen?

p.s. - I'm using Microsoft Visual c++ 2010 express

Did you try running the executable produced by compiling your program? — Frédéric Hamidi, Jul 26 '13 at 12:03
If it compiles, [ship it!](http://www.amazon.com/Practical-Guide-Successful-Software-Projects/dp/0974514047) — sehe, Jul 26 '13 at 12:06
You should probably learn a thing or two about compilation... — undu, Jul 26 '13 at 12:07
and then you'll also want to know this: [Why is the console window closing immediately without displaying my output?](http://stackoverflow.com/q/8868338) — Cody Gray - on strike, Jul 26 '13 at 12:14
It seems that somebody has copied your code and made a [video for you](http://www.youtube.com/watch?v=LRcoKAkg8mI). Nice! — podkova, Jul 26 '13 at 12:10

Modify your code to

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

What will this do that it will ask for a character input from you before exiting the console.

It runs even better if you put the `getchar()` call *before* the `return` statement :-P – Angew is no longer proud of SO Jul 26 '13 at 12:08

In fact, use `std::cin.get();` - seems more idiomatic – user123 Jul 26 '13 at 12:08
That should be `std::getchar` in C++. – Bartek Banachewicz Jul 26 '13 at 12:10
Err, actually, the best solution would be `std::cin.ignore()`. – Cody Gray - on strike Jul 26 '13 at 12:12
@Saksham [so] is not about being really fast or first. – Bartek Banachewicz Jul 26 '13 at 12:12
Yes, actually, @CodyGray is right. `std::cin.ignore()` would be better – user123 Jul 26 '13 at 12:14

C++ standard doesn't have any mention of `getch()` function. – Bartek Banachewicz Jul 26 '13 at 12:10
