Learning C through K&R book

I already compiled and ran my first code but there's this thing.
When I run it, cmd flashes and disapears.(I'm using Dev-C++ on windows to make it)
Anyways, I think there was a command or function to make the cmd pause till I press enter or something like that so that I am able to read whatever the output was, the thing is, I cant remember the name of the function or how to write it.
Can one of you tell me which it is, if there is one.
BTW here's my code:


#include <stdio.h>

main ()
{
  printf("Hello World!");
}

>>38
The arguments and the type for main() wasn't in the book so I didn't put that there.
Mind if I ask why you put those there and why those seem to stop the getchar() thing from pausing the cmd so I can see the result of my code?
