Example of the keypad: INSTRUCTIONS A 12 B 34 C 56 D 78 # 9 10 I cons Once a user has selected their drink the system should allow them to enter the amount of money they are inserting into the machine. The program should then calculate the amount of change to be returned and subtract one from the number of the drink in the machine. If the user selects a drink which has sold out an appropriate message should be displayed. Some input validation should be carried out on the selection from the true table. Arrays must be used and an expected looping menu-structure of the keypad.

The program should then calculate the amount of change to be returned from the machine
