Overloading = Operators
nWhenever there is dynamic memory allocated on an object-by-object basis in a class, we should overload
the assignment operator
for the same reasons that require the
copy constructor
nThe assignment operator
must be overloaded as a member,
and it doesn’t modify the second operand (so if it is an object of a class -- it should be a const
ref.)
nThe assignment operator
can be chained, so it should return
an lvalued object, by reference
nIt modifies the current object, so it cannot be a const member function
