c continue loop

"Prompt user to enter 'c' to continue or 'q' to quit"

How do I add that code into my program, thanks alot!
I figure it has to be a typa loop?! i was thinking a while loop but when i tried that it did not work.

main() { puts("enter 'c' to continue or 'q' to quit"); }

Homework done, given the specifications.
