Jason opened a coffee shop at the beach and sells coffee in three sizes: small (9oz), medium (12oz), and large (15oz). 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: a. b. c. d. 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. Your program should consist of at least the following functions: a function to show the user how to use the program, a function to sell coffee, a function to show the number of cups of each size sold, a function to show the total amount of coffee sold, and a function to show the total money made. Your program should not use any global variables and special values such as coffee cup sizes and cost of a coffee cup must be declared as named constants.
