Write a C++ program to create a base class called shape. Use this class to store two double type value that could be used to compute the area of figures. Derive two specific classes called traingle and rectangle form the base shape. Add to the base calss, a member function get_data() to initialize base class data members and another member function display_area() to compute and display the area of figures. Make display_area() as a virtual function and redefine this function in derived classes to suit their requirements.

Write a C++ program to create base class called number with an integer data member and a member function to set the value for this data member. Derive three classes from this base class called hexadecimal, decimal and octal. Included a member function show() in all these three derive classes to display the value of the base class data member in hexadecimal, decimal and octal respectively. Use the concept of pure virtual functions.
