Project Requirements

Create a monitoring program for a vending machine. The program will be used to insure that the candy vending machine in the S-wing at BCC is always full.

Main Menu

At startup, a main menu appears. This menu allows the user to select between 3 options:

1. Customer – the hungry overworked student who needs some “quick sugar energy” to continue working.

2. Vendor – the owner of the machine. If vendor is selected, an id and password will be requested and validated against a saved id/password.

3. Exit – A process initiated by the BCC Public Safety Officer on his rounds at 11:00 PM that saves the current inventory in the vending machine and terminates the program until the next morning.

Customer Menu

The Customer menu provides two options:

1. List Items – This choice displays a list of all candy in stock in the machine and the corresponding ID number.

a. Only items with a quantity greater than zero are displayed.

2. Buy – This choice allows the user to specify one item by ID number.

a. Display a list of candy in stock and the ID numbers – i.e. call List Items (#1)

b. The ID number must be a valid entry.

c. There need be at least one of that candy item in stock.

d. Purchase price will be displayed (all candy sells for $1.00 or less).

e. The customer will enter the amount of money in coins (quarters, dimes, and nickels only) to represent the actual feeding of the vending machine. Ex: 2 quarters, 2 dimes, 1 nickel.

f. The program will display the change due the customer and will provide a “dispense candy” message such as “Eat and enjoy” or “Don’t work too hard”.

g. The quantity for that item must be decreased by 1.

3. Return to Main Menu – Displays the Main Menu

Vendor Menu

This is a more complex menu.

1. New Item – Permits the entry of a new candy item that was not previously sold.

a. The item name, quantity added, and price must be entered.

b. The program must assign the item an ID number.

c. Only 10 items fit in the machine. You cannot add an 11^th item.

2. Delete Item – Removes the item from the vending machine.

a. The ID number of the item needs to be entered.

b. You may only delete an item if the quantity is 0.

3. Add Inventory – Update the quantity

a. The ID number and quantity being ADDED or SUBTRACTED is specified

b. The quantity cannot exceed 5 for any particular type of candy.

c. The quantity must be at least zero.

4. Update Price – Allows modification to the sales price of the candy.

a. The ID number and new price must be specified.

b. The price must be at least $ .25

c. The price cannot exceed $1.00

5. Detail Report – Display a nicely formatted table for each item regardless of its quantity (quantity of zero is included).

a. Item code

b. Item name

c. Quantity

d. Price

6. Exception Report – Display a nicely formatted table for items that need to be filled immediately (quantity is less than 2).

a. Item Code

b. Item name

c. Quantity

7. Return to Main Menu – Displays the Main Menu

Additional Operations

1. Initialize Data – When the program begins, the item information must be read from a text file.

2. Save Data – When Exit is selected from the Main Menu, the current information must be written to a text file. This is the file that will be read by Initialize Data when the program is run again.

Data Types:

The basic candy information is:

· Item ID number

· Item name

· Quantity

· Price

There is a maximum of 10 different candy items in the vending machine at any given time. You may choose to store this information in one of the following data types:

· An array of pointers to a struct – Each menu activity must be implemented as a separate function.

· An array of structs – Each menu activity must be implemented as a separate function.

· An array of objects. Each object contains the items mentioned above and the methods for manipulating the items. Not every menu item need become a method. Implement the others using functions. The coding is much simpler using this implementation.

· A set of parallel arrays – This implementation will require the most source code.

Note: This is a professional business application. Your menu should be designed accordingly. Your code must meet professional standards with regard to comments, identifiers, and style. Test each facet of your Monitoring System (all possibilities) to be sure it works. Have a friend try the system to insure that they cannot "break it".

Phase I:

Decide which data type(s) you will be using. Prepare flowcharts, pseudocode, of N-S charts that document your logic in solving this problem. Remember that logic is shown separately for each function. Review your analysis and flowcharts with me for approval. My signature is needed before you begin to code. You will submit this documentation with your project.

Phase II:

Code your program. See me in class and during office hours for assistance. Send e-mail with your questions. Since you will be using a modular approach, I suggest that you code and test one section at a time. If you need help in determining the proper starting point, ask!

Phase III:

Test your program as a complete unit. Be sure to test all possibilities. Have a friend try your program to insure that they cannot “break it”. You may wish to discuss appropriate test input with me.

Phase IV:

Submit working project. You MUST be able to answer questions regarding the design and your particular implementation of the design in C++. Submission of a working project is required to pass the course.
