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 “Sub1” (Derive features in public mode). In sub1, there is a member function in public section: get_data1 () to take input for x, and define Task () in this class to display the factorial of x. [Implement the above program by creating pointer to base in main () function and call the necessary functions]. Write the program in c++ language.
