Design a class named Box whose dimensions are integers and private to the class. The dimensions are labelled: length 1, breadth b, and height h. The default constructor of the class should initialize 1, b, and h to 0. The parameterized constructor Box(int length, int breadth, int height) should initialize Box's 1, b and h to length, breadth and height. The copy constructor Box (Box B) should set 1, b and h to B's 1, b and h, respectively. Apart from the above, the class should have 4 functions: 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 the operator #include... 4 //Implement the class Box 5 1/1,b,h are integers representing the dimensions of the box 6 7 // The class should have the following functions : 8 9 // Constructors: 10 // Box(); 11 // Box (int, int, int); 12 // Box (Box); 13 14 15 16 17 // 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 18 19 //overload operator >n; Box temp; for(int i=0;i>type; if(type ==1) { cout>1>>>>h; Box NewBox (1,b,h); temp=NewBox; cout>1>>b>>h; Box NewBox(1,b,h); if(NewBox
