exceptions

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

polymorphism

An actual instance of a function is created in memory when the compiler encounters

a call to the template function

The line: virtual double earnings() const = 0; appears in a class definition. You CAN NOT deduce that;

all classes derived from this class will override this method.

Using inheritance allows us to

all of the above: 1. eliminate duplicate code 2. make our classes more modular 3. us polymorphism

Abstract classes

are defined, but the programmer never intends to instance any objects from them.

If a base class has public member functions that are not listed by a derived class, then these functions

are inherited unchanged in the derived class

Which of the following assignments would be a compilation error?

The ______ constructer is called before the _________ constructer.

base, derived

Which of the following would not be a member function that derived classes Fish, Frog, and Bird should inherit from the base class Animal and then provide their own definitions for so that the function call can be preform polymorphism.

the try block

The correct order in which an exception is detected and handled is:

try, throw, catch

__________ functions are dynamically bound by the compiler

virtual

A ________ of a base class expects to be overridden in a derived class

virtual function

Polymorphism is implemented via:

virtual functions and dynamic binding

An exception thrown from outside a try block

will cause the program to abort execution

yes
