you know that "Press any key to exit" thing that pops up when your ready to exit. how do i take that out and put my own i have.

Code:
	char cExit;

	do //do whats in the brackets
	{
	  printf("To exit press Q\n");

	  cExit = getch();
	  cExit = toupper(cExit);

	  if (cExit == 'Q')
	  printf("Bye!\n\n");
	}
	  
	while(cExit !='Q');//until the letter q or Q is pressed
now all i need it to exit when that key is pressed. how can i do my own exit. with out any api or anything like that.
