8.1.6.Using pointers to structure objects: delete the point

#include <iostream>

using std::cout;

using std::endl;



struct Box {

  double length;

  double width;

  double height;



  double volume();

};



double Box::volume() {

  return length * width * height;

}





int main() {

  Box aBox = { 1, 2, 3 };

  Box* pBox = &aBox;

 

  Box* pBox2 = new Box;

  pBox2->height = pBox->height+5.0;

  pBox2->length = pBox->length+3.0;

  pBox2->width = pBox->width+2.0;

  cout << "Volume of Box in the free store is " << pBox2->volume() << endl;



  delete pBox;

  delete pBox2;

  return 0;

}

Volume of Box in the free store is 128
