This is a design for a class named Box whose dimensions are integers and private to the class. The dimensions are labeled: length I, breadth b, and height h The default constructor of the class should initialize I, b, and h 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 Box(Box B) should set l.b and h to B's I.b and h, respectively Every constructor should increment the global variable BoxesCreated. The destructor should increment the global variable BoxesDestroyed. Apart from the constructor and destructor, the class should have 4 functions: int getLength)- Return box's length int getBreadth Return box's breadth int getHeight0 Return box's height long long CalculateVolume) Return the volume of the box Overload the operator 'for the class Box. "Box A Box B" if Overload operator
