Considering the above scenario, you are required to write a C++ program containing three classes: Stockltem, Handouts and LectureDVD, where Stockltem should be the base class, and Handouts and LectureDVD should be its derived classes. You are required to use the concept of Polymorphism to generate the sample output. The detail of data members and member functions for each class is provided in the given table. Solution Guidelines: You have to use the concept of Polymorphism to generate the sample output given and submit the screenshot of your output
