Operator Overloading
nBinary operators
have either a single argument if they are overloaded as members (the first operand corresponds to the implicit this pointer
and is therefore an object
of the class in which it is defined)
nOr, binary operators
have two operands if they are overloaded
as non-members
ä(where there is no implicit
first operand)
nIn this latter case,
it is typical to declare the operators as friends of the
class(es) they apply to -- so that they can have access privileges to the private/protected data members without going thru the public client interface.
