Imagine a publishing company that markets both book and audio-cassette versions of its works. Create a class publication that stores the title and price of a publication.

Each of these three classes should have set() and get() functions and a display() function to display its data. Write a main() program to test the book and tape class by creating instances of them, asking the user to fill in their data and then displaying the data with display().
