[solved] – Question 88980

Start with the program of Exercise 1 in this chapter, and add a member function of typeboolcalledisOversize()to the bookandtapeclasses. Let’s say that a book with morethan 800 pages, or a tape with a playing time longer than 90 minutes (which wouldrequire two cassettes), is considered oversize. You can access this function from main()and display the string “Oversize” for oversize books and tapes when you display theirother data. If bookandtapeobjects are to be accessed using pointers to them that arestored in an array of type publication, what do you need to add to the publicationbase class? Can you instantiate members of this base class?
