Jason opened a coffee shop at the beach and sells coffee in

Jason opened a coffee shop at the beach and sells coffee in three sizes: small (9 oz), medium (12 oz), and large (15 oz). The cost of one small cup is $1.75, one medium cup is $1.90, and one large cup is $2.00. Write a menu-driven program that will make the coffee shop operational. Your program should allow the user to do the following:

Buy coffee in any size and in any number of cups.

At any time show the total number of cups of each size sold.

At any time show the total amount of coffee sold.

At any time show the total money made.
