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 $3\mathrm{.}14159$

The class will have the following member functions:

$1.$ Default Constructor that sets the radius to $0\mathrm{.}0($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 circle$$s 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 $3\mathrm{.}14159$ 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.
