Write a complete C++ program which will produce the sample runs shown at the end.
You will first ask the user to choose a school (ASU or UA) or to quit the program. If a school is
chosen, display a menu to access that school's vending machine. Below are the menus and the
starting amounts for each product.
[school] Vending Machine Main Menu
-----------------------------
A. Get Soda - $ 1.25
B. Change Brand
C. Restock Soda
D. Leave This Machine
-----------------------------
[school] Vending Machine
------------------------
Type Stock
------------------------
Coke 10
Orange 8
Dew 6
Ice Tea 4
Evian 1
The following is an explanation of each menu choice:
Get Soda
This menu choice displays the vending machine. It lists out the 6 different sodas available and how
many are in stock.
See the list above for starting types and amounts.
Change Brand
This allows the user to swap out one soda for a different brand of soda. The user will be prompted
for the new soda's name and the name of the old soda to be replaced. The new soda will begin with
five (5) cans of soda. If the user does not type in the exact name of the old soda, an error message
will display, because the program will not be able to match the names. The user may not remove
the Coke. This will be one of your assumptions.
Restock Soda
The user will type in the name of the soda to be restocked. If the user does not type in the exact
name of the old soda, an error message will display, because the program will not be able to match
the names. If there is a soda name match, the user can restock the soda with 20 cans.
Leave this menu
Leaves the menu and again asks for a school or quit the program.
If the user choose to quit the program, the program states Whose machine has more Coke left and
how many Cokes each school has. (See the Sample Runs below.)
All user input must be error checked. If it is out of range, an appropriate error message must be
generated and the user must be prompted again. String input is case sensitive while character input
is case insensitive. (See the Sample Runs below.)
Assignment 4 p 1/6
You may wish to use the following two system calls. Each is a simple statement.
system("CLS");
This command will clear the screen.
system("PAUSE");
This command will pause the screen. Great for displaying reports. This command causes the
onscreen message of "Press any key to continue . . ." in the following sample output. Once the
user presses any key, the program will continue.
