8. Circle Class 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 Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career. 

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
