Constructors in Hierarchies
nThe arguments to the base
class constructor can only consist
of values supplied as arguments to the derived class constructor, constants, literals, global
variables, or expressions
made up from such values.
nWe cannot use derived
class data members as arguments
to a base class constructor nor can we invoke a member function of the derived class and use its return value as one of the actual arguments
äbecause the
derived class has not yet been initialized.
