Question: 1 / 565

What can potentially happen if the signature of a redefined member function in a derived class changes from the base class version?

It creates a new function

It overloads the existing function

It hides the base class version

When the signature of a redefined member function in a derived class changes from the base class version, a new function is not created and it does not overload the existing function. Instead, it hides the base class version, meaning that the base class function cannot be accessed through an object of the derived class unless it is explicitly specified. This can potentially lead to unexpected behavior, as the derived class function may have different functionality than the base class function. Changing the signature of a redefined member function in a derived class should be done with caution and careful consideration of the potential impact on the code.
