Answer 1

Not understanding plz

Answer 2

Answer:

#include <iostream>

using namespace std;

class box

{

  private:

     int area,volume,height,width,length;

  public:

      void operator ++()  

      {  

          height=10;

          width=20;

          length=20;

      }

      void Area(){ cout<<"area is"<<2*(height*width+height*length+width*length);  }

      void Volume() { cout<<"Volume is "<<height*width*length; }

       

};

int main()

{

   box t;

   // this calls "function void operator ++()" function  

++t;  

   t.Area();

   t.Volume();

   return 0;

}

Explanation:

here operator "++ "overloading is used to just initialize the height width and length its called at ++t and the other member functions are doing their own job as said area and volume.
