I have created the base class below, but am having an issue with the second half of the question that requires me to incorporate the base class into the new program. This base class needs to be implemented as a header and included in main.

You are now working for a department store, and your task is to create a point-of-sale application to allow customers to calculate the total cost of their sale including taxes.

Using C++ object-oriented programming (OOP), the base class, Simplemath, has the following derived classes within: Addition, Subtraction, Division, Multiplication. The user has the option to choose which calculation he or she prefers to use.

Create a C++ program that does the following:

Calculates sales tax and total cost based on the type of purchased product using the following categories and tax percentages:

Category 1 - Clothing: 6%

Category 2 - Beauty products: 7%

Category 3 - Grocery: 3%

Category 4 - Gardening: 6%

Category 5 - School supplies: 3%

Category 6 - Tobacco products: 10%

Creates an array to store the numbers users input and uses the switch statement to calculate the sales tax and final cost based on the category of the purchased product

Prompts the user for category and price of the product

Calculates and displays the final cost
