What is the relationship into which a subclass must fit whenever inheritance is used? Provide at least three examples that illustrate this relationship.
What will be an ideal response?
Whenever inheritance is used, the subclass must fit into an "is-a" relationship with the base class. For example, an on-campus student (subclass) is a student (base class). A subclass is always in an "is-a" relationship with the base class. Further examples include: An hourly worker (subclass) is an employee (base class); a scholarship athlete (subclass) is a student (base class); a computer teacher (subclass) is a faculty member (base class).
