Question

Write a C++ Program to solve the following problem:

A vendor sells different products which include Books and Software.
Create an abstract base class named Product which has three protected members (code, description and price). Product class contains one virtual function called displayProduct() (returns specific product information) which will be overridden by its derived classes (Book and Software). Besides inheriting from its base class, Book has author field, Software has version field. Write Constructors (including copy constructor), getter for each data member and one setData() function to set the values for all fields, Create an array of pointer which points to each product instance and display the product information in a loop. You can give fixed value to test your classes.

please use the members given... thank you so much in advance.
