Answer to Question #205578 in C++ for Ali

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.

· add virtual functions of calculateSurfaceArea() and calculateVolume() in ThreeDimensionalShape

Implement all functions in child classes Sphere, cube, and tetrahedron.

Answer 1

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