Create a class author with attributes name and qualification. Also create a class publication with pname. From these classes derive a class book having attribute title and price. Each of the three classes should have a getdata() method to get their data from user. The classes should have putdata( ) method to display the data. Create instances of the class book in main.

#include #include using namespace std; class Author { private: string name; string qualification; public: void getdata() { cout << 'Enter author name: '; getline(cin, name); cout << 'Enter author qualification: '; getline(cin, qualification); } void putdata() { cout << 'Author name: ' << name << endl; cout << 'Author qualification: ' << qualification << endl; } }; class Publication { private: string pname; public: void getdata() { cout << 'Enter publication name: '; getline(cin, pname); } void putdata() { cout << 'Publication name: ' << pname << endl; } }; class Book : public Publication { private: string title; float price; public: void getdata() { Publication::getdata(); cout << 'Enter book title: '; getline(cin, title); cout << 'Enter book price: '; cin >> price; } void putdata() { Publication::putdata(); cout << 'Book title: ' << title << endl; cout << 'Book price: ' << price << endl; } }; int main() { Book b; b.getdata(); b.putdata(); return 0; } In the Author class, we have two private attributes name and qualification. The getdata() method prompts the user to input values for these attributes, which are stored in the object's data members. The putdata() method displays the author's name and qualification. The Publication class has a single private attribute pname for the publication name. The getdata() and putdata() methods for this class function similarly to the Author class. The Book class is derived from the Publication class, and has two private attributes title and price. The getdata() method first calls Publication::getdata() to get the publication name, and then prompts the user to enter the book title and price, which are stored in the object's data members. The putdata() method first calls Publication::putdata() to display the publication name, and then displays the book's title and price. In the main() function, we create an instance of the Book class, call its getdata() method to get the user input, and then call its putdata() method to display the entered data.
