title: The program needs to keep looping till the key "Q"/"q" is typed
body: <p>The program extracts the digit and I want it to keep looping till the key "Q" / "q" is typed by the user. For example when the user hits the "O" key, the program should print the ones digit of the number they inputted and so on for any 3-digit number the user inputs. When I run the code right now, there is no output but there is also no error. </p>
