Box it! - Hacker Rank Solution
Problem
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:
- A.l < B.l
- B.b < B.b and A.l == B.l
- 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 :
0 <= l,b,h <= 10^5
Two boxes being compared using the < operator will not have all three
dimensions equal.
