Vending Machine Simulator

[rpierre2]

The program should create an array of five structures. Each time the program runs, it should read the data from the input file ("DrinkMachineInventory.txt") and then enter a loop that performs the following steps:

Display the list of drinks, cost, and the number of drinks in the machine.
The user should be allowed to either quit the program or pick a drink. If the user selects a drink, he or she will next enter the amount of money that is to be inserted into the drink machine. The program should display the amount of change that would be returned and subtract one from the number of that drink left in the machine. If the user selects a drink that has sold out, a message should be displayed. The loop then repeats. When the user chooses to quit the program it should display the total amount of money the machine earned.

Lost have no idea what to do.
