Question

In a c++ program, Implement a Pyramid class with base and height as data members and surface area() and volume() calculations as member functions.

Answer 1

// C++ code
#include <iostream>
#include <cstdlib>
#include <math.h>
using namespace std;

class Pyramid
{
   private:
       double base;
       double height;
       double length;
   public:
       Pyramid()
       {
           base = 0 ;
           height = 0;
       }

       Pyramid(double b, double ht)
       {
           base = b;
           height = ht;
       }

       double surface_area()
       {
           return 0.5*(base*height);
       }

       double volume()
       {
           return (base*height);
       }

};

int main()
{
   Pyramid p(3,4);

   cout << "surface_area: " << p.surface_area() << endl;
   cout << "volume: " << p.volume() << endl;

}
/*
output:

surface_area: 6
volume: 12

*/
