Design a class named Box whose dimensions are integers and private to the class. The dimensions are labelled: length l, 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 Box (const Box& 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:
1. A.l < B.l
2. A.b < B.b and Al. == B.l
3. A.h < B.h and A.b == B.b and == A.l == 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.
Constraints:
l, b and h are in the range of [0, 100000].
Two boxes being compared using the operator will not have all three dimensions equal.
2. Please implement your Box class in box.hpp. You only need to submit box.hpp and your report in this assignment.
