Identify what should be common among the derived classes:
For polymorphic behavior, the base class should declare a function that makes sense for all derived classes. In this case, common actions for animals might include actions likeand . -
Examine each provided function:
-
: This is appropriate since all animals (Fish, Frog, Bird) move, albeit in different ways. -
: This is also applicable, as all animals sleep. -
: This function is specific to animals with wings. Fish and Frogs generally do not have wings, so they would not be able to implement this function in any meaningful way.
-
-
Conclusion:
Since the base class Animal should define common functions that all derived classes can override,is the function that should not be inherited for polymorphic behavior.

In the fascinating world of polymorphism, derived classes like Fish, Frog, and Bird inherit behaviors from the base class Animal but might not all share the same functionality. “flapWings” would not be a function that Fish or Frog would need to inherit because they don’t possess wings. Fish swim, frogs hop, and birds flap their wings, showing that while some behaviors are shared, others are uniquely tailored to each animal’s capabilities.
When designing member functions, it’s essential to remember that not every animal behaves the same way. For instance, if “move” is meant to be overridden by the individual classes to account for their unique locomotion methods—swimming for Fish, hopping for Frog, and flying for Bird—it serves as a great example of polymorphism. Ensuring each derived class has its own meaningful implementation is key to effective and engaging object-oriented design!
