Question

Note- can you please rewrite the code in C++

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

Answer 1

The code in C++ is given below along with the screenshot of the output.

#include <iostream>

using namespace std;

class Circle

{

private:

//private attribute (variable)

float radius;

public:

float area;

//setter

void setRadius(int r)

{

radius = r;

}

//getter

float getRadius()

{

return radius;

}

float getArea() //function that returns area of circle

{

area = 3.14159*getRadius()*getRadius();//formula to calculate area

return area;

}

};

int main()

{

Circle var;

var.setRadius(5); //set the value of radius

std::cout << "\nRadius = " << var.getRadius();

std::cout << "\nArea = "<<var.getArea();

return 0;

}
