Hello coders, In this post, you will learn how to solve the Box it! Hacker Rank Solution. This problem is a part of the HackerRank C++ Programming Series.
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 <= 10^5Two boxes being compared using the < operator will not have all three dimensions equal.
