Question

This is a design for a class named Box whose dimensions are integers and private to the class. The dimension are labeled: length I, breadth b, and height h. The default constructor of the class should initialize I, b, and h to O The parameterized constructor Boxfint length, int breadth, int height) should initialize Box's l,b and h to lengt breadth and height. The copy constructor Box(Box B) should set l,b and h to B's l.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 getBreadth0) - Return box's breadth int getHeight0 Return box's height long long CalculateVolume) - Return the volume of the box Overload the operator'

Explanation / Answer

It is the software design phase of a software development lifecycle.

A precondition expresses the constraints under which a method will function properly.  A postcondition expresses properties of the state resulting from a method's execution.

Here, by the above definition of Box, we have the following pre-conditions:

by the above definition of Box, we have the following post-conditions:
