Circle Class (Easy)
Write a Circle class that has the following member variables:
radius : a double
The class should have the following member functions:
Default Constructor: default constructor that sets radius to 0.0.
Constructor: accepts the radius of the circle as an argument.
setRadius: an 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
getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius
Step1: Create a declaration of the class.
Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating
Circle objects, and then reporting the circle’s area, and circumference.
You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…
A nonmember function must be declared as a(n)_________ of a class to have access tothat class’s private data members.

- writte in c++ 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 • getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radiusarrow_forwardWrite base class with the name Shape . The Shape class have Private Variable: area, a double used to hold the shape's area. Public Member Functions: getArea the Accessor. This function should return the value in the member variable area. Parameterized constructor—Initializes area member. Defualt constructor— Empty body calcArea. This function should be a incomplete function.Next, define a class named Triangle . It should be child of Shape class. It should have the following members:Protected Member Variables: base, a integer used to hold the base of triangle.Height, a integer used to hold the height of the triangle. Public Member Functions: constructor—Initializes values for base, height. The overridden calcArea function in Circle described below.calcArea—calculates the area of the Triangle (1/2* base * height) and stores the result in the inherited member area.After you have created these classes, create a driver program that defines a Triangle object. Demonstrate that each object…arrow_forwardDouble Bubble For this exercise you need to create a Bubble class and construct two instances of the Bubble object. You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…arrow_forward
