Q2/ Create class BOX that have three data members (length, height, and width). And the following function members: • Default Constructor to initialize the data members. • Input: to input values to the data members. • Print: to display the data members values. • Overload (=) operation to assign the values of one BOX objects to another. • Friend f…
