Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.
Allows for code reusability by creating a new class based on an existing class
Derived class (subclass) inherits properties and behaviors from a base class (superclass)
Can have multiple levels of inheritance, creating a hierarchy of classes
Example: Animal class can be a base class with Dog and Cat
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or classes.
Examples include method overloading and method overriding in object-oriented programming.
