$13.$ Drink Machine Simulator

Write a program that simulates a soft drink machine. The program should use a

structure that stores the following data:

Drink Name

Drink Cost

Number of Drinks in Machine

The program should create an array of five structures. The elements should be

initialized with the following data:

Drink Name Cost Number in Machine

$-------------------------------------$

Cola $\mathrm{.}7520$

Root Beer $\mathrm{.}7520$

Lemon$-$Lime $\mathrm{.}7520$

Grape Soda $\mathrm{.}8020$

Cream Soda $\mathrm{.}8020$

Each time the program runs, it should enter a loop that performs the following

steps: A list of drinks is displayed on the screen. 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.

Input Validation: When the user enters an amount of money, do not accept

negative values, or values greater than $$1\mathrm{.}00.$

Use the following function prototypes:

int getChoice$($Drink $[])$;

void transaction$($Drink $[],$ int, double &$)$;
