Question
Write a program that simulates the functionality of a vending machine having the following characteristics:
- The vending machine offers 5 products
- The vending machine accepts coins, 1 dollar bills, and 5 dollar bills
- The change is always given in coins, with maximum possible number of coins in each value: 25, 10, 5 or 1 cent.
- The selections available for user are numbers from 1 to 5.
- The user enters the money – simulate the action through a loop that ends when the user enters 0. Each coin, or paper bill will be read individually.
- The user makes the selection, and the machine allows a maximum 4 other selections if the amount entered doesn’t cover the price of the item.
- Once an item is delivered, the machine gives the change in coins.
- There is no increment for the money during one selection.
- The user can stop the selection at any time by entering 0 for the product selection.
- If the user chooses to cancel the selection, the machine returns the initial amount in coins.
- Display the outcome of the operation for each alternative you consider possible for the vending machine.
- Make sure that the machine returns the correct change at all times.
Use appropriate selection and repetition loops to solve the problem.
