Download the files Box.h, Box.cpp, client.cpp from Canvas. The Box class contain length, breadth, and height as member variables. The class supports several operations on these member variables as: adding the variables of two boxes, increasing/decreasing the member variables, outputting the variables and assign the variables to another box object. Read the given code. Then implement these member and non-member functions in Box.cpp file. You do not need to edit the Box.h and client.cpp files.

Below are the given codes:

Box.h

#include using namespace std;

class Box { public:

Box(); // default constructor Box(double, double, double); // parameter constructor double getVolume(); void setLength(double length); void setBreadth(double breadth); void setHeight(double height);

Box operator+(Box const&); // addition operator overload, member function Box& operator++(); // pre-increment operator overload, member function

private: double length; // Length of a box double breadth; // Breadth of a box double height; // Height of a box

friend ostream& operator

}; Box.cpp

#include using namespace std;

class Box { public:

Box(); // default constructor Box(double, double, double); // parameter constructor double getVolume(); void setLength(double length); void setBreadth(double breadth); void setHeight(double height);

Box operator+(Box const&); // addition operator overload, member function Box& operator++(); // pre-increment operator overload, member function

private: double length; // Length of a box double breadth; // Breadth of a box double height; // Height of a box

friend ostream& operator

}; 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

// Get the volume of Box1 volume = Box1.getVolume(); cout

Box1 = ++Box1; 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

// Get the volume of Box2 volume = Box2.getVolume(); cout

Box2 = --Box2; cout

// Get the new volume of Box2 volume = Box2.getVolume(); cout

// Add two Boxes as follows: Box3 = Box1 + Box2;

cout

// Get the volume of Box3 volume = Box3.getVolume(); cout

return 0; }

Output:
