What is polymorphism, and how can it be achieved? Please provide an example.

Question

Accepted Answer

Polymorphism is the ability of a function or method to behave differently based on the object it is called with.

Polymorphism can be achieved in object-oriented programming through method overriding and method overloading.
Method overriding allows a subclass to provide a specific implementation of a method that is already provided by its superclass.
Method overloading allows multiple methods in the same class to have the same name but different parameters.
Example: Inheritance in Java allows for polymorphism, where a superclass reference can point to a subclass object and call overridden methods.
Example: Method overloading in C++ allows for polymorphism, where multiple functions with the same name but different parameters can be called.
