Answer to Question #156212 in C++ for GELO

Question

In the form of Object-Oriented programming, create an equivalent program of the program from the first one. Create new source file and copy the given second program from. below

FIRST PROGRAM:

#include <iostream>

#include <cmath>

using namespace std;

void getArea(int length, int width, int radius) {

int recta;

float cira;

recta = length * width;

cira = 3.1416 * pow(radius, 2);

cout << "Area of Rectangle: " << recta << endl;

cout << "Area of Circle: " << cira << endl;

}

int main() {

int rectlength, rectwidth, cirradius;

cout << "Enter length of a Rectangle: ";

cin >> rectlength;

cout << "Enter width of a Rectangle: ";

cin >> rectwidth;

cout << "Enter radius of a Circle: ";

cin >> cirradius;

getArea(rectlength, rectwidth, cirradius);

return 0;

}

SECOND:#include <iostream>

#include <cmath>

using namespace std;

class Rectangle {

public:

int length, width;

double getArea(void) {

return length * width;

}

};

class Circle {

public:

int radius;

double getArea(void) {

return 3.1416 * pow(radius, 2);

}

};;

int main(){

Rectangle R;

Circle A;

cout << "Enter length of a Rectangle: ";

cin >> R.length;

cout << "Enter width of a Rectangle: ";

cin >> R.width;

cout << "Enter radius of a Circle: ";

cin >> A.radius;

cout << "Area of a Rectangle = " << R.getArea() << endl;

cout << "Area of a Circle = " << A.getArea() << endl;

}

#include <iostream>

using namespace std;
class Area {
    public : 
        int length;
        int width;
        int radius;
    void getParametrs() {
        cout << "Enter length of a Rectangle: ";
        cin >> length;
        cout << "Enter width of a Rectangle: ";
        cin >> width;
        cout << "Enter radius of a Circle: ";
        cin >> radius;
    }
};
class Rectangle : public Area {
    public :

        void getAreaCircle() {
            cout << "Area of Rectangle: " << 3.1416 * pow(radius, 2);
        }
};
int main () {
    Rectangle rectangle;
    Circle circle;
    rectangle.getParametrsRectangle();
