Question

#include <iostream>
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())<<endl;
// printing area of circle
cout<<"Area of circle is: "<<(myCircle.getArea())<<endl;
return 0;

}

1. Write a statement that defines an array of five objects of the Circle class in the above statement. Let the default constructor execute for each element of the array.

Answer 1

Please find the required code below.

Cricle myCircles[5];

This statement will create an array of five objects of Circle class. And, by default, the default constructor is called for each of the Circle object.
