Question

the reserved word virtual is used with a base-class member function to alert the c compiler that it must determine the actual member function to call at run-time. thus derived classes can have their own (possibly completely different) versions of the base-class function. when a base-class defines a member function to be virtual, what should each derived class do?

Answer 1

Each derived class should override the virtual member function in the base class, by implementing a new version of the function with the same signature.

What is function?

A function is a self-contained block of code that performs a specific task and returns a result. Functions are used to keep code organized, reduce code duplication, and increase code readability. Functions can take parameters, which are values passed in from outside the function, and can return results, which are values sent back from the function. Functions are often used to perform complex calculations, and are reusable, meaning they can be called multiple times from different parts of a program.

This will allow the compiler to determine which version of the function should be called at run-time, based on the type of object used to make the function call. By overriding the virtual member function in the derived class, the derived class can provide its own implementation of the function which may be different from the base class version.
