Summary of "Object Oriented Programming (OOP) in C++ Course"
Main Ideas:
- Introduction to OOP:
- Object-Oriented Programming (OOP) is a programming paradigm that uses objects to represent real-life entities, encapsulating their attributes and behaviors.
- OOP allows for more intuitive problem-solving by modeling real-world scenarios.
- Basic Concepts:
- Classes and Objects:
- A class is a user-defined data type that serves as a blueprint for creating objects.
- Objects are instances of classes that hold specific data and can perform functions defined in their class.
- Attributes and Behaviors:
- Attributes are characteristics of an object (e.g., a car's manufacturer, color, price).
- Behaviors are actions that an object can perform (e.g., a car can drive, stop).
- Classes and Objects:
- Access Modifiers:
- Private: Members are accessible only within the class.
- Public: Members can be accessed from outside the class.
- Protected: Members are accessible in derived classes.
- Constructors:
- A constructor is a special method invoked when an object is created, used to initialize attributes.
- Encapsulation:
- Encapsulation is the bundling of data (attributes) and methods (behaviors) that operate on that data within a class, restricting direct access to some of the object's components.
- Abstraction:
- Abstraction hides complex implementation details and exposes only the necessary parts of an object to the user.
- Inheritance:
- Inheritance allows a class (derived class) to inherit attributes and behaviors from another class (base class), promoting code reuse and logical hierarchy.
- Polymorphism:
- Polymorphism allows methods to do different things based on the object that it is acting upon, enabling a single interface to represent different underlying forms (data types).
Methodology/Instructions:
- Creating a Class:
- Define a class using the
classkeyword, and include attributes and methods. - Use access modifiers to control visibility.
- Define a class using the
- Using Constructors:
- Create a constructor to initialize object attributes when an object is instantiated.
- Implementing Encapsulation:
- Make class attributes private and provide public getter and setter methods to access and modify them.
- Implementing Inheritance:
- Use the
class DerivedClass : public BaseClasssyntax to inherit from a base class. - Ensure derived classes call the base class constructor to initialize inherited attributes.
- Use the
- Implementing Polymorphism:
- Define a method in the base class as
virtualto allow derived classes to override it with their own implementations.
- Define a method in the base class as
