Imagine a publishing company that markets both book and audiocassette versions of its works. Create a structure publication that stores the title (a string) and price (type float) of a publication. From this structure nest two structures: book, which adds a page count (type int), and tape, which adds a playing time in minutes (type float). Each of these three structures should have a getdata() function to get its data from the user at the keyboard, and a putdata() function to display its data.Write a main() program to test the book and tape structures by creating instances of them,asking the user to fill in data with getdata(), and then displaying the data with putdata().
