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.
This project is a simple modification of Project 5 from Chapter 2. Three if statements are added to detect invalid input: less than 25 cents, more than a dollar, and not a multiple of 5 cents.
