Probably a while loop or a do loop, as in:
do {
printf("Enter number:\n");
/* ... */
printf("press c to continue or q to quit");
} while (getchar == 'c');
I know you didn't ask about it, but fflush(stdin) has undefined
behavior. If you'll tell us what you're really trying to accomplish
with it, we may be able to tell you something you can do instead
(though there's no guarantee of it).
