Program Using C.

A vending machine sells three kinds of candy, Airheads for 25 cents, Fun Dip for 40 cents, and Gummi Bears for 20 cents. Write a program that will simulate this vending machine. First, accept coins from the user (user enters #of cents as integers 5, 10, or 25), until the user enters zero. Then give the user a choice (with menu) for candies. If the user enters an invalid choice, display a Invalid selection message. If the amount deposited is sufficient, print the selection and calculate and display the change. If the amount deposited is not sufficient, display a message for insufficient amount and return the money.
