Write your question here.
Hi, this is my very first post on this website, and unfortunately I need some help with writing a program for a c++ class. Hopefully I'll be able to return the favor at some point. Here's the problem:
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 of coffee 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. Buy coffee in any size and in any number of cups.
b. At any time show the total number of cups of each size sold.
c. At any time show the total amount of coffee sold.
d. 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.

I'm having so much trouble with functions. I could do this program without any trouble without any trouble if I didn't have to use them! I'm currently getting an error message that says "tutorial function does not take 6 arguments." and I really don't know why. I also just in general don't understand functions and reference variables very well, so if this program is a total train wreck design wise, that's why. Any help would be appreciated.
