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 labeled: length l, breadth b, and height h.
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<<"Lesser\n"; } else { cout<<"Greater\n"; } } if(type==4) { cout<<temp.CalculateVolume()<<endl; } if(type==5) { Box NewBox(temp); cout<<NewBox<<endl; } } } int main() { check2(); }

please explain the operator overloading part.
ReplyDeletewhich part you need to explain < function or << function
DeletePlease explain the << function.
DeleteThanks a lot!!!
ReplyDeleteseveral points are incorrect in your code:
ReplyDelete1. in constructor prefer the `:` for the assignation
2. all the get method and the calculate should be marked as `const`
3. when you pass the Box in the operators they should be const too
