# HackerRank C++ Box It!

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 ,hand 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 BoxBox 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 getHeight() - Return box's height
long long CalculateVolume() - Return the volume of the box

```#include<bits/stdc++.h>

using namespace std;

class Box {
private:
public:
Box() {
length = 0;
height = 0;
}
Box(int l, int b, int h) {
length = l;
height = h;
}
Box(const Box &B) {
length = B.length;
height = B.height;
}
int getLength() {
return length;
}
}
int getHeight() {
return height;
}
long long CalculateVolume() {
return (long long)(breadth) * length * height;
}
bool operator<(Box &B) {
if (length < B.length) {
return true;
} else if (length == B.length) {
return true;
if (height < B.height) {
return true;
}
}
}

return false;
}
};
ostream &operator<<(ostream &out, Box &B) {
out << B.getLength() << " " << B.getBreadth() << " " << B.getHeight();
return out;
};

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()
