Hello Programmers, In this post, you will know how to solve the Box it! HackerRank Solution. This problem is a part of the HackerRank C++ Programming Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Box it! HackerRank 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.
