Solution :
#include<bits/stdc++.h>
using namespace std;
//Implement the class Box
class Box{
private:
int l,b,h;
public :
Box():l(0),b(0),h(0){
}
Box(int l , int b , int h){
this->l = l;
this->b = b;
this->h = h;
}
Box(Box & obj){
l = obj.l;
b = obj.b;
h = obj.h;
}
int getLength(){
return l;
}
int getBreadth(){
return b;
}
int getHeight(){
return h;
}
long long CalculateVolume(){
return long(l)*long(b)*long(h);
}
bool operator<(Box& b){
if (this->l < b.l){ return true;}
else if (this->b < b.b && this->l == b.l) { return true;}
else if (this->h < b.h && this->b ==b.b && this->l == b.l){return true;}
return false;
}
friend ostream& operator<<(ostream& out, Box& B){
out << B.l <<" "<<B.b<<" "<<B.h;
return out;
}
};
//l,b,h are integers representing the dimensions of the box
// The class should have the following functions :
// Constructors:
// Box();
// Box(int,int,int);
// Box(Box);
// 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 operator < as specified
//bool operator<(Box& b)
//Overload operator << as specified
//ostream& operator<<(ostream& out, Box& B)
