    class book{
        protected:
            string title;
            string author;

            book(string title, string author)
            : author(author), title(title) {}
    };
    
    class MyBook: book {
        private:
            double price;
        public:
            MyBook(string author,string title, double price)
            : book(author, title), price(price) {}
        
            void display(){
                 cout<<"Title: "<<title<<endl;
                 cout<<"Author: "<<author<<endl;

C# is here...:)

class MyBook  : Book
 {
     int Price { get; set; }
    
     public MyBook(string title, string author, int price) : base(title, author)
     {
         Price = price;
     }


     public override void display()
     {
         Console.WriteLine($"Title: {title}");
         Console.WriteLine($"Author: {author}");
         Console.WriteLine($"Price: {Price}");
     }

 }

class MyBook extends Book {

        int price;

            MyBook(String title ,String author, int price)
   {
      super(title,author);
      this.price=price; 
   }

   public void display()
   {
       System.out.println("Title: "+title);
       System.out.println("Author: "+author);
       System.out.println("Price: "+price);
   }

My C++ solution:

#include <string>
#include <iostream>
using namespace std;

class Book{
private:
    string title;
    string author;

protected:
    string getTitle() const {
        return title;
    }
    
    string getAuthor() const {
        return author;
    }
    
public:
    Book(string title, string author) :
    title(title), author(author) {}
    
    virtual void display() = 0;
};


class MyBook: Book{
private:
    int price;
public:
    MyBook(string title, string author, int price) :
    Book(title, author), price(price) {}
    
    void display() {
        cout << "Title: " << getTitle() << endl
        << "Author: " << getAuthor() << endl
        << "Price: " << price << endl;
    }
};


int main() {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */
    string title,author;
    getline(cin,title);
    getline(cin,author);
    
    int price;
    cin >> price;
    
    MyBook b(title,author,price);
    b.display();   
    
    return 0;
}
