Create a circle class in a separate header file that has the following private member variables:
1. Radius: a double
2. Pi: a double initialized to 3.14159
The class will have the following member functions:
1. Default Constructor that sets the radius to 0.0(even though the program does not use it)
2. A Constructor that accepts the radius of the circle as an argument (the program will use this)
3. setRadius a mutator function for the radius variable
4. getRadius an accessor function for the radius variable
5. getArea returns the area of the circle (area = pi * radius * radius)
6. getDiameter returns the diameter of the circle ( diameter = radius *2)
7. getCircumference returns the circumference of the circle (circ =2* pi * radius)
Requirements:
Using the main function on the next page, write a program that demonstrates the circle class by
prompting the user for the circles radius (with input validation), create a circle object using the
overloaded constructor, and then report the area, diameter, and circumference with the output
precision set to (2) two decimal places. Use a separate header file for the class. Add a UML Diagram for
the class as a comment below main (10%).
The program will:
Use a separate *.h file for the class and a *.cpp file for main.
Use 3.14159 as the value for pi
Include #ifndef and #endif directives as required
Have a UML diagram of the Class with access specifiers, parameters, and return types (ref Figure
13-22 pg 826) as a comment below main.

// CLASS NAME
//**********************************
// MEMBER VARIABLES

//**********************************
// MEMBER FUNCTIONS
//(with access specifiers, parameters,
// and return types)
//**********************************
Grading will be based on meeting all of the lab requirements, adherence to programming standards,
operation and accurate output, and programming style including white space and indentation.

Sample Main:
// Chapter 13, Programming Challenge 8: Circle Class
int main()
{
double radius =0; // To hold a radius
// Get the radius.
while (radius <=0)
{
cout << "Enter the circle's radius: ";
cin >> radius;
if(radius <=0)
cout << "That is not a valid radius." << endl >
