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 (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.
