How can I make it pause before closing the program output window?

I'm compiling some test programs on a windows-based system, and the windows
containing my program's output are closing so quickly after my program calls
exit that I can't see the output. How can I make it pause before closing?

After wondering why the author of your compiler's run-time system didn't
take care of this for you, simply add the lines

printf("Hit RETURN to exit"n");

fflush(stdout); (void)getchar();

just before the end of your program. (If you want to wait for any keystroke, not
just the RETURN key
