Hi, Runtime time polymorphism is done using inheritance and virtual functions. Method overriding is called runtime polymorphism. It is also called late binding. When overriding a method, you change the behavior of the method for the derived class. Overloading a method simply involves having another method with the same prototype. When and why to use method overloading Use method overloading in situation where you want a class to be able to do something, but there is more than one possibility for what information is supplied to the method that carries out the task. You should consider overloading a method when you for some reason need a couple of methods that take different parameters, but conceptually do the same thing. Method Overriding: Whereas Overriding means changing the functionality of a method without changing the signature. We can override a function in base class by creating a similar function in derived class. This is done by using virtual/override keywords.
