Inheritance in C++ | Program for Inheriting book and audio cassette version class from a base class as Publishing Company with Exception Handling in CPP

 Problem Statement: Imagine a publishing company which does marketing for book and audio cassette versions. Create a class publication that stores the title (a string) and price (type float) of publications. From this class derive two classes: book which adds a page count (type int) and tape which adds a playing time in minutes (type float).

Write a program that instantiates the book and tape class, allows user to enter data and displays the data members. If an exception is caught, replace all the data member values with zero values.
