Imagine a publishing company that markets both books and audio-cassette versions of its works. Create a class publication that stores the title (a string) and price (type float) of a publication. From this class derive two classes: book with which adds a page count (type int) and tape which adds a playing time in minutes (type float). Each of these three classes should have a getData() function to get its data from the user at the keyboard and a putData() function to display its data.
