Exam 15: Inheritance

When we derive one class from another class, this is known as ____________

If a base class has a public member function, and the derived class has a member function with the same name, but with a different parameter list, this function is said to be

Member functions defined as private in the base class are/are not) inherited in the derived class

Polymorphism refers to

Given a class A that derives from a class B that derives from a class C, when an object of class A goes out of scope, in which order are the destructors called?

A base class may have at most _______ child class derived from it.

If a derived class Class2) has redefined a function from the base class Class 1), how can that derived function call the base class function if the function declaration is as follows? Void print );

If the member variables of the base class are marked as protected, who can access those variables?

Given the following classes and code, what is the output of the last statement shown? Class Pet { Public: Virtual void print); String name; Private: }; Class Dog: public Pet { Public: Void print); String breed; }; Void Pet::print) { Cout << "My name is " << name; } Void Dog::print) { Pet::print); Cout << ", and my breed is a "<< breed << endl; } Pet* pPtr; Dog* dPtr=new Dog; DPtr->name= "Rover"; DPtr->breed="Weiner"; PPtr= dPtr; PPtr->print);

The ability to associate multiple meanings to one function name using dynamic binding is called _________.

If the member variables in a base class are private, then

If you use the keyword virtual in a function declaration, you must also use it in the function definition.

The base class has everything that is in the derived class and more

What is another name for a child class?

In the derived class definition, you list from the base class

A derived class pointer can point to

If you have a copy constructor in the base class, but do not have a copy constructor for the derived class, then

Using virtual functions is also known as _______ the functions

Which of the following should be virtual if a base class uses dynamic memory allocation?

If a base class has a non-virtual member function named print, and a pointer variable of that class is pointing to a derived object, then the code ptr->print ); calls
