Summary
These lecture notes cover the concept of polymorphism in C++. The notes provide an example of a base class Animal with a method called animalSound() and how derived classes (like Pig, Cat, Dog) can override this method to implement their specific animal sounds. Polymorphism allows different objects to have different behaviors while sharing a common interface.

C++ Polymorphism The word “polymorphism” means having many forms. In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form. A real-life example of polymorphism is a person who at the same time can have different characteristics. A man at the same time is a father, a husband, and an employee. So the same person exhibits different behavior in different situations. This is called polymorphism. Polymorphism is considered one of the important features of Object-Oriented Programming. For example, think of a base class called Animal that has a method called animalSound(). Derived classes of Animals could be Pigs, Cats, Dogs, Birds - And they also have their own implementation of an animal sound (the pig oinks, and the cat meows, etc.): Example #include using namespace std; // Base class class Animal { public: void animalSound() { cout
