Write a class definition called Circle that stores an instance variable named radius for the radius of the circle as float. Write the corresponding getter and setter methods (getRadius, setRadius), and a constructor that takes a float parameter for the radius of the circle.
Include both the class declaration and method definitions! Be sure to use appropriate visibility modifiers.
Assume all includes and using namespace std are already in the file. Do not try to make header files.

#include <iostream>
#include <string>
using namespace std;
class circle{
private:
double radiuss;
public:
circle(double rad) {
radiuss=rad;
}
circle(){
radiuss=0;
}
double get_radius() {
return radiuss;
}
void set_radius(double rad){
radiuss=rad;
}
double get_area() {
return radiuss*radiuss*3.14;
}
};
int main()
{
circle c1(1.1);
c1.set_radius(1.4);
cout<<“radius of circle is:”<<c1.get_area();
return 0;
}
output:
/* constructor with parameter and constructor withoout parameters are written and getters and setters and area method is implemented
*/
