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!");
}

>>40
Why does batch have a function to pause the program till acknowledged but C which is supposed to be OH SO GREAT doesn't?

And it's not the same at all.  He removed the "getchar()" and added "int argc, char *argv[]" and that "ANUS" crap".
Anyways, I added the gerchar and when I ran it, it wouldn't stay open.  I think it has something to do with "int argc, char *argv[]" but I do not know.
