3. Write a program to create a base class: "Question3", with protected data member: x (int) and with pure virtual function: “Task ()" [Returns no value and takes no argument]. Create a derived class of "Question3" such as "Subl" (Derive features in public mode). In sub1, there is a member function in public section: get_datal () to take input for x, and define Task () in this class to display the reverse of x. [Implement the above program by creating pointer to base in main () function and call the necessary functions].

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
