Exam 15: Inheritance, Polymorphism, and Virtual Functions

A member function of a derived class may not have the same name as a member function of a base class.

When you derive a class from an existing class, you _________ add new data and functions.

A derived class may not have any classes derived from it.

The base class access specification can be viewed as a filter that base class members must pass through when becoming inherited members of a derived class.

A virtual function is a member function that expects to be _________ in a derived class.

When more than one class is derived from a base class, the situation is called:

A derived class may become a base class, if another class is derived from it.

Polymorphism is when ____________ in a class hierarchy perform differently, depending upon which object performs the call.

The base class's __________ affects the way its members are inherited by the derived class.

The term __________ means the ability to take many forms.

____________ is commonly used to extend a class, or to give it additional capabilities.

The base class access specification determines how ___________ members in the base class may be accessed by derived classes.

A __________ of a base class expects to be overridden in a derived class.

Arguments are passed to the base class destructor function by the ________ class __________ function.

_________ members of a base class are never accessible to a derived class.

When arguments must be passed to the base class constructor, they are passed from the derived class constructor's header line.

The compiler performs __________ on virtual functions.

When member functions behave differently, depending upon which object performed the call, this is an example of ___________.

__________ functions are dynamically bound by the compiler.

_________ allows us to create new classes based on existing classes.
