Question

·       Implement the following hierarchy.

·       Make Shape, TwoDimensionalShape, and ThreeDimensionalShape as abstract class

·       Add virtual functions of calculateArea() and perimeter() in TwoDimensionalShape.

·       Implement the above functions in child classes Circle, Square , Triangle. Take help from Google to find the formulas.

Answer 1

#include <iostream>
using namespace std;
class Shape{
    
};
class TwoDimensionalShape{
    virtual double calculateArea()=0; 
    virtual double perimeter()=0;
};
class ThreeDimensionalShape{
    
};


//classes Circle, Square
class Circle{
    int r;
    public:
        double calculateArea(){
            return (3.142*r*r);
        }
        double perimeter(){
            return (2*3.142*r);
        }
};
class Square{
    int s;
    public:
        double calculateArea(){
            return (s*s);
        }
        double perimeter(){
            return (4*s);
        }
};
class Triangle{
    double b,h,hy;
    public:
        double calculateArea(){
            return (0.5*b*h);
        }
        double perimeter(){
            return (b+h+hy);
        }
};
int main()
{
    
    return 0;
}
