Online Shopping Store - Programming Project - Assignment - Spring 2024

This assignment requires the creation of an online shopping store program. The program must handle customer registration, assign unique IDs, and track purchase history to determine discount levels. It needs to manage a product inventory, display warnings for out-of-stock items, and calculate subtotals, discounts, taxes, and the final total. The program should generate a receipt and save it to a text file. Additionally, a manager function is required, protected by a password, which allows for viewing inventory and restocking products. The project emphasizes the use of classes, inheritance, and text files for data storage, and it should provide a user-friendly experience. The assignment also encourages referencing online store models like Amazon and Walmart for inspiration and requires the program to handle potential errors gracefully.

In this Assignment, you will create your own on-line shopping store in the console application.
You can choose different products to sell in your store (at least 8 products). You will create an
product inventory text file.
The program will display two options at the beginning of the program, Customer and Manager.
Customer:
If this is a new customer, the program will let customer to register with their
information and assign a unique ID number to the new customer.
The customer will enter the customer id every time when they are shopping in your
store and the program will keep tracking the total amount the customer spend each
time to determine the discount level. You can create your discount level rule or use the
rule in the assignment 4.
The program has to keep tracking the products inventory. If customer select the product
that is out of stock, the program has to display a warning message and let customer
continue to shop. After customer finish selecting the products, the program will
calculate the subtotal, apply the discount, calculate the tax, and the total. The program
will display a receipt on the screen and save it to a text file with customer information.
(Just like the HEB receipt).
Manager:
The manager option has to be password protected. The program will give the manager
two option:
1. Display the inventory: display all the products stock information
2. Restock the products: add more stock for each product
You have to create different classes and utilize the inheritance features. You have to text files to
keep all the information the program need. You can check some on-line store to get some ideas
(Amazon, Walmart …). Make sure your program does not end unexpectedly and let user have
the option to continue.
