Box It Hackerrank Solution in C++

Box It Hackerrank Solution in C++. Design a class named Box whose dimensions are integers and private to the class. The dimensions are labelled: length, breadth b, and height h. The default constructor of the class should initialize l, b, and h to 0. The parameterized constructor Box(int length, int breadth, int height) should initialize Box's l, b and h to length, breadth and height.

The copy constructor BoxBox B) should set l, b and h to B's l, b and h, respectively.

Apart from the above, the class should have 4 functions:

int getLength() - Return box's length
int getBreadth() - Return box's breadth
int getHeight() - Return box's height
long long CalculateVolume() - Return the volume of the box

Overload the operator for the class Box. Box A < Box B if:

A.l < B.l
A.b < B.b and A.l==B.l
A.h < H.h and A.b==B.b and B.b==B.l

Overload operator << for the class Box().

If B is an object of class Box:

cout<<B should print B.l, B.b and B.h on a single line separated by spaces.

For example,

Box b1; // Should set b1.l = b1.b = b1.h = 0;

Box b2(2, 3, 4); // Should set b1.l = 2, b1.b = 3, b1.h = 4;

b2.getLength(); // Should return 2

b2.getBreadth(); // Should return 3

b2.getheight(); // Should return 4

b2.CalculateVolume(); // Should return 24

bool x = (b1 < b2); // Should return true based on the conditions given

cout<<b2; // Should print 2 3 4 in order.

Constraints

0 <= l, b, h <= 10^5

Two boxes being compared using the < operator will not have all three dimensions equal.

#include <bits/stdc++.h>
using namespace std;
//Implement the class Box  
//l,b,h are integers representing the dimensions of the box

// The class should have the following functions : 

// Constructors: 
// Box();
// Box(int,int,int);
// Box(Box);

// int getLength();	// Return box's length
// int getBreadth ();	// Return box's breadth
// int getHeight (); 	//Return box's height
// long long CalculateVolume();	// Return the volume of the box

//Overload operator < as specified
//bool operator<(Box& b)

//Overload operator<<as specified
//ostream& operator<<(ostream& out, Box& B)
