“Vending Machine Simulator”

Note: This coursework constitutes 40% of your total assessment in this module

Tasks

Develop a simulator for a high-tech vending machine. On the screen, the user can view the

product selection, price and quantity available. Customer can choose whether to pay using

Wechat or Aliplay. For simplicity, assume that the vending machine only has 9 types of product

item for sales.

The following data should be used to establish the initial state of the machine:

Table 1: Initial Product Inventory

Item Name Price (Yuan) Initial Quantity

Sprite 3 10

Coca Cola 3 10

Pepsi 3 10

Orange 3 10

Lemon Tea 5 10

Coffee 6 10

Milk Tea 6 10

Green Tea 5 10

Mineral Water 2 10

*Note: Initial quantity above is also the maximum quantity the machine can store for each item.

In your program, store the item objects in an array. Design at least 2 classes, a ProductItem

class and a VendingMachine class to implement the simulator. A ProductItem’s object can

be defined using the members listed in Table 2.

Table 2: Members of ProductItem class

No. Function/Variable Description Type

1 itemName The name of the item string

2 itemCost Cost of item in yuan double

3 itemQuantity Quantity of the item available for sale integer

4 Member functions Relevant assessors and mutators

functions. Don’t forget constructor,

destructor and copy constructor.

The VendingMachine class should have the members listed in Table 3.

Table 3: Members of VendingMachine class

No. Function/variable Description

1 Constructor Constructor which initialises the inventory using the data in Table

1.

2 menuDisplay A function that allows the machine to display product, price and

quantity available. During the purchasing process, the display

should show the status from selection till dispensing of the item.

An option to cancel is also required. There should be a special side

menu that enables the machine operator to enter the

maintenance mode.

3 buyItem A function that allows user to start purchasing. The customer is

allowed to buy more than one item per transaction. Provide the

right condition to handle the purchase when it is out of stock.

4 refill_Item A function under the maintenance mode that allows operator to

refill item. Provide the right condition to prevent mistake. Also take

note of the maximum quantity. This menu is only accessible by the

machine operator.

5 salesReport A function that allows the machine to produce a report of the sales

on the screen and also print the statement to a textfile with

filename “YY-MM-DD.txt”. This menu is only accessible by the

machine operator.

6 Other functions An excellent assignment should include advanced features which

are not stated above. Also, don’t forget to implement copy

constructor and destructor.

Important Notes

(1) Create a UML (class) diagram using PPT and save in PDF format. Please note that member

variables and functions listed in Table 2 and 3 are not exhaustive.

(2) Demonstrate a good understanding on how to use array, pointer, dynamic memory allocation

and access control to member variables and functions in your program.

(3) Provide adequate comments to enhance the readability of your codes.

(4) The simulator should be implemented as a multi-file program (*.h, *.cpp and main.cpp).

(5) Submission deadline is 9 MAY 2023, 5PM. ZIP (not RAR) your codes and UML diagram into

one folder and upload to Moodle. 10% will be deducted per day of late submission.
