- Write a C++ program that implements the geometric shape “rectangle” as an object. For that, you should decide the data members that represent the object first, and then you should write the necessary member functions for the correct operation of the class. The class declaration should also include at least one constructor function. Remember that, for a rectangle, we can calculate the area, circumference, and diagonal length. You should define all member functions within the class declaration. Test all member functions written! Try to define member functions outside the class declaration.MUST MATCH OUTPUT AS IT IS. ---------------------------------------- Write a C++ program to call static and non-static member functions. Strictly adhere to the Object-Oriented specifications given in the problem statement.

Furthermore: The Employee class should keep track of how many employees (objects) have been created inthe system. Your Employee class should initialize all of its fields via a constructor. Create function prototypes to set and get an employee's zip code. Declare a print_employee() function that prints all of an employee object's details.(Whenever possible, use constant functions.)

- WRITE A PROGRAM IN C++ Create a Circle class with a centre (x,y) and radius r. Use parameterized constructor to initialize the radius and centre of a circle object. Write a copy constructor that copies the values of one circle object to another one. Use a member function to display the values x,y,r of a circle object. Allow a friend function to update the centre and radius of the circle. There should a static variable 'number_of_circles' and a static member function 'update_number_of_circles' which will update the 'number_of_circles' whenever an instance of a circle is created.
