Chapter 15: Problem 23

Fill-in-the-Blank When a derived class redefines a function in a base class, which version of the function do objects that are defined of the base class call? __________

Short Answer

Expert verified

Answer: Objects of the base class call the version of the function in the base class.

Step by step solution

Understand the terms involved

In object-oriented programming, classes act as a blueprint to create objects. A derived class is a class that is created by inheriting members (properties or functions) from a base class. When a derived class has a function with the same name (and the same parameters) as one in the base class, this is called function overriding. This allows the derived class to provide a specific implementation for that function.

Answer the question

According to the question, we are asked about objects that are defined of the base class. When a derived class redefines a function in the base class, this will have no impact on objects of the base class. Objects of the base class will always call the version of the function defined in the base class itself. The overridden function in the derived class will only be called for objects of the derived class or its subclasses. So, the answer is "Objects of the base class call the version of the function in the base class."
