Question

In this project VENDO. We are going to use Structs and maybe Enums that we learned about today.

Your job is to write code to simulate a vending machine with at least ten products in it. Stock the vending machine with three of each item. Stock the coin machine with three of each coin. To acquire items from the vending machine you must first ask the user which item they wish to purchase. If item requested is out of stock report that item is not available. If item is in stock ask them to report on the coins or bills they placed in the machine. Once they give you the amount of coins or bills, you must report on whether or not the translaction is possible. If it is not possible return their coins and bills and advise them to use correct change . If it is possible vend the item and make change using the minimum number of coins. Announce the calorie content of the item to make them feel guilty (or not). Report on the inventory of the vending machine. Report on the inventory of the coin machine. Ask for another transaction?
