C exercise -Switch case

Define a menu function dispMenu (defined below) which will let the user select which exercise to demo. The user can quit with q or Q. The user can stay within a particular exercises function until they quit with a sentinel code that you choose.

// returns menu choice 1 to n. Define n choices for now. You can change n to whatever you need it to be. int dispMenu();
