Which of the following would not be a member function that derived classes Fish, Frog and Bird should inherit from base class Animal and then provide their own definitions for, so that the function call can be performed polymorphically? eat sleep flapWings

In the world of animal behavior, functions like `eat` and `sleep` are fundamental aspects shared across various species, making them perfect candidates for polymorphic behavior. On the flip side, `flapWings` is unique to flying creatures, which means it's not applicable to all derived classes. Therefore, it wouldn't make sense for Frog and Fish to inherit or redefine this method, as they simply don’t have wings to flap! When designing your class hierarchy, remember to identify traits that are common across all derived classes for your polymorphic functions. Failing to do so could lead to confusion and unnecessary complexity in your code. Make sure to keep your inheritance structure clean and focused on shared behaviors!
