Answer to Question #284301 in C++ for amna

Question

Start with the publication, book and tape classes. Add base class sales that holds an array of three floats so that it can record the dollar sales of a particular publication for the last three months. Include a getdata() function to get three sale amount from the user and a putdata() function to display the sales figure. Alter the book and tape classes, so they are derived from both publication and sales. An object of book or tape should input and output and sales data along with other data. Write a main function to create a book and tape object and exercise their input/output capabilities
