//Implement the class Box  
//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
