There is something to be taken care in destructor, in copy
constructor, suppose the memory is assigned to the embedded
member object pointer with the parameter passed value, but
if some other objects of different class also are pointing
to this memory, then if some one deletes the object then
this class member pointer object will become dangling, or
if the object is not deleted properly then there will be
memory leak. Please suggest the design change required to
handle or avoid this situation What is overloading in oops? Is this job good for future?
