/*
Design a class named Box whose dimensions are integers and private to the class. The dimensions are labelled: length , breadth , and height .
The default constructor of the class should initialize , , and to .
The parameterized constructor Box(int length, int breadth, int height) should initialize Box's and to length, breadth and height.
The copy constructor BoxBox ) should set and to 's and , respectively.
Apart from the above, the class should have 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 for the class Box. Box Box if:
<
< and ==
< and == and ==
Overload operator for the class Box().
If is an object of class Box:
should print , and on a single line separated by spaces.
Constraints
Two boxes being compared using the operator will not have all three dimensions equal.
