Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the radius variable, and a function named getArea that returns the area of the circle. The area is calculated as: 3.14159 * radius * radius

See explaination

Explanation:

#include

using namespace std;

class Circle{

/ / private member variable named radius

private:

double radius;

/ / get function for radius

public:

double getRadius () {

return radius;

}

/ / set function for radius

void setRadius (double rad) {

radius=rad;

}

/ / returning area = 3.14159 * radius * radius

double getArea () {

return (3.14159 * radius * radius);

}

};

/ / Sample run

int main ()

{

/ / Declaring object of Circle

Circle myCircle;

myCircle. setRadius (5);

/ / printing radius of circle

cout<<"Radius of circle is: "<< (myCircle. getRadius ()) <
/ / printing area of circle

cout<<"Area of circle is: "<< (myCircle. getArea ()) <
return 0;

}
