C++ Programming

Write a Circle class that has the following member variables: radius : a double pi : a double initialized with the value 3.14159 The class should have the following member functions: Default Constructor. A default constructor that sets radius to 0.0. Constructor. Accepts the radius of the circle as an argument. setRadius. A mutator function for the radius variable. getRadius. An accessor function for the radius variable. getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius getDiameter. Returns the diameter of the circle, which is calculated as diameter = radius * 2 getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius

* Create 2 Circle objects (one using default constuctor, one by passing in a non 0, positive arugment, using non-pointer circle variables. Call the getArea, getDiameter and getCircumference methods and diplay the results.

* Write a destructor that simply has a cout statement noting the circle is being destroyed

* Create a pointer to a Circle, create a new Circle object with a non zero positive radius and set the pointer to point to it.

* delete the memory for this newly created circle (you should see the destructor message when running)

* Call the circle get Area, Diameter and Circumference methods using the pointer to a circle and display the results.

Write a program that demonstrates the Circle class by asking the user for the circles radius, creating a Circle object, and then reporting the circles area, diameter, and circumference.
