Polymorphism is implemented via: Member functions. inline functions. von-virtual functions and dynamic binding.

Polymorphism is famously implemented using virtual functions, where a base class declares virtual methods, and derived classes override these methods. This allows for dynamic binding at runtime, meaning that the program can decide which method to invoke based on the object being pointed to at that moment, enabling flexible and reusable code structures. A common pitfall when working with polymorphism is forgetting to use the "virtual" keyword in the base class. If you don't declare the function as virtual, the program will not recognize the derived class's methods and will invoke the base class's methods instead, leading to unexpected behavior. Always ensure that your base methods that you expect to override are declared as virtual!
