HackerRank Box It! solution in c++ programming YASH PAL, 31 July 202422 August 2024 In this HackerRank Box It! problem in c++ programming language you need to 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 lengthint getBreadth() – Return box’s breadthint getHeight() – Return box’s heightlong long CalculateVolume() – Return the volume of the boxOverload the operator < for the class Box. Box A < Box B if:A.l < B.lA.b < B.b and A.l==B.lA.h < B.h and A.b==B.b and A.l==B.lOverload 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.HackerRank Box It! problem solution in c++ programming.#include<bits/stdc++.h> using namespace std; class Box { private: int l,b,h; public: Box() { l = b = h = 0; } Box(int length,int breadth,int height) { l = length; b = breadth; h = height; } Box(const Box& B) { l = B.l; b = B.b; h = B.h; } int getLength() { return(l); } int getBreadth() { return(b); } int getHeight() { return(h); } long long CalculateVolume() { return ((long long)l*b*h); } friend bool operator < (Box& b1, Box& b2) { if((b1.l < b2.l) || (b1.l == b2.l && b1.b < b2.b) || (b1.l == b2.l && b1.b == b2.b && b1.h <b2.h)) return(true); else return(false); } friend ostream& operator << (ostream& s,Box& b1) { s << b1.l << " " << b1.b << " " << b1.h; return s; } }; void check2() { int n; cin>>n; Box temp; for(int i=0;i<n;i++) { int type; cin>>type; if(type ==1) { cout<<temp<<endl; } if(type == 2) { int l,b,h; cin>>l>>b>>h; Box NewBox(l,b,h); temp=NewBox; cout<<temp<<endl; } if(type==3) { int l,b,h; cin>>l>>b>>h; Box NewBox(l,b,h); if(NewBox<temp) { cout<<"Lessern"; } else { cout<<"Greatern"; } } if(type==4) { cout<<temp.CalculateVolume()<<endl; } if(type==5) { Box NewBox(temp); cout<<NewBox<<endl; } } } int main() { check2(); } C++ Programming Tutorials coding problems solutions Hackerrank Problems Solutions
