Question:
Modify Programming Project 5 from Chapter 2 to check the validity of input data. Valid input is no less than 25 cents, no more than 100 cents, and an integer multiple of 5 cents. Compute the change only if a valid price is entered. Otherwise, print separate error messages for any of the following invalid inputs: a price under 25 cents, a price that is not an integer multiple of 5, and a price that is more than a dollar.
Programming Project 5 from Chapter 2
Write a program that determines the change to be dispensed from a vending machine. An item in the machine can cost between 25 cents and a dollar, in 5 cent increments (25, 30, 35, … , 90, 95, or 100), and the machine accepts only a single dollar bill to pay for the item. For example, a possible dialogue with the user might be
Enter price of item
(from 25 cents to a dollar, in 5-cent increments): 45
You bought an item for 45 cents and gave me a dollar,
so your change is
2 quarters,
0 dimes, and
1 nickel.
