Program language: C++ A publishing company markets both hardcopy and eBook versions of its work. Create a class publication that stores the title and price of a publication. From this class derive two classes: book, which adds a page count, and digital, which adds a storage capacity in MG bytes. Each of these classes should have a getdata() function to get its data from the user at the keyboard and put a putdata() function to display its data. Add a base class sales that hold 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 sales amounts from the user and a putdata() function to display the sales figures. Modify the book and digital classes so they are derived from both publication and sales. An object of the class book or digital should input and output sales data along with its other data. Write the main function to create a book object and a digital object and test their input and output capabilities.

Use the following main function to test the program:
#include "Sale.h"
#include "Publication.h"
#include "Book.h"
#include "Digital.h"
#include <iostream>
#include <string>
using namespace std;
int main() {
Book book;
Digital digital;
book.getData();
book.putData();
cout << endl;
digital.getData();
digital.putData();
cout << endl;
return 0;
}
