The document discusses key concepts of object-oriented programming in C++, including classes and objects, encapsulation, abstraction, inheritance, and polymorphism. Classes are blueprints that are used to create objects which contain data and functions. Encapsulation binds data and functions together and uses access modifiers. Inheritance allows code reusability by deriving a class from a base class. Polymorphism enables one name with multiple implementations through function overloading and overriding.

3. Introduction to OOP
 OOP stands for Object-Oriented Programming
 OOP models real-world entities as objects
 Objects contain data (attributes) and functions (methods)
 C++ fully supports OOP since C++11 standard

4. Classes and Objects
 A class is user defined blueprint or prototype from
 Objects are called instance of a class.
 Class represents set of properties and method.
 Objects can store state and exhibit behavior.
which objects are created.

8. Encapsulation
 Binding data and functions into a single unit is encapsulation
 Class attributes can be declared private
 Private attributes can only be accessed via public member
functions
 Prevents direct modification of object state

9. Abstraction
 Hiding internal implementation details
 Showing only essential features to user
 Achieved through abstract classes and interfaces
 Provides reusability

10. Inheritance
 Inheritance allows a derived class to acquire attributes and methods of a base
class
 Provides reusability of code
 Supported by public, protected and private inheritance
 Can be single, multilevel or multiple inheritance

11. Polymorphism
 Having many forms - one name, multiple implementations
 achieved through function overloading and overriding
 Compile-time polymorphism with function overloading
 Runtime polymorphism with virtual functions

12. Summary
 OOP makes code reusable and modular
 Classes, objects, inheritance and polymorphism are key concepts
 Abstractions like abstract classes hide details
 C++ fully supports OOP since C++11 standard
