Need help with C++

Use Client.cpp and Box.h to complete the Todo statements on Box.cpp

CLIENT.CPP

#include "Box.h"

int main() {

Box Box1; // Instantiate Box1 of type Box

Box Box2; // Instantiate Box2 of type Box

Box Box3; // Instantiate Box3 of type Box

double volume = 0.0; // Store the volume of a box here

// Box1 specification

Box1.setLength(6.0);

Box1.setBreadth(7.0);

Box1.setHeight(5.0);

cout

cout

// Get the volume of Box1

volume = Box1.getVolume();

cout

Box1 = ++Box1;

cout

cout

// Get the new volume of Box1

volume = Box1.getVolume();

cout

// Box2 specification

Box2.setLength(12.0);

Box2.setBreadth(13.0);

Box2.setHeight(10.0);

cout

cout

// Get the volume of Box2

volume = Box2.getVolume();

cout

Box2 = --Box2;

cout

cout

// Get the new volume of Box2

volume = Box2.getVolume();

cout

// Add two Boxes as follows:

Box3 = Box1 + Box2;

cout

cout

// Get the volume of Box3

volume = Box3.getVolume();

cout

return 0;

}

Box.h

sample output :
