Object-Oriented Programming (OOP) in C++

C++ supports Object-Oriented Programming (OOP), a paradigm that focuses on data rather than functions.
OOP structures software entities (objects) and enables them to interact with each other.
A class binds data and functions into a single unit, acting as a blueprint for objects.
Classes define properties (data) and behaviors (functions) an object of that class should have.

Classes and Objects

A class is a blueprint for objects, while an object is an instance of a class.
Constructors are special functions in a class that are called when creating an object.
There are three types of constructors: default, parameterized, and copy constructors.
Default constructors do not require any arguments and are used to initialize objects with default values.
Parameterized constructors allow properties to be set to custom values at the time of object creation.
Copy constructors are used when creating a new object and initializing it with the values of an existing object.

Destructors and Encapsulation

Destructors are special functions that are called when an object is deleted or goes out of scope.
Destructors are used to perform cleanup, such as releasing system resources acquired during the object's lifetime.
Encapsulation is a key property of OOP, allowing data and functions to be bundled together.
Encapsulation hides the complexity of implementation details while only exposing the necessary information.

Abstraction and Inheritance

Abstraction provides a way to hide complex implementation details and only present essential features.
Inheritance enables a class to inherit properties from another class.
A parent class/super class is the class whose properties are inherited.
A child class/subclass is the class that inherits properties from the parent class.
Inheritance reduces code repetition and increases reusability.

Polymorphism and Access Specifiers

Polymorphism is the ability of an object or method to take different forms depending on the context.
Access specifiers (public, private, and protected) determine the accessibility of class members.
Public members are accessible anywhere in the code.
Protected members are accessible only in the parent and child classes.
Private members are only accessible within the same class.

Inheritance Modes and Types

Inheritance modes (public, private, and protected) determine how inherited properties are accessed in the child class.
There are five types of inheritance: single, multi-level, multiple, hierarchical, and hybrid inheritance.
Single inheritance occurs when a child class inherits properties from one parent class.
Multi-level inheritance occurs when a child class inherits from a parent class that also inherits from another class.
Multiple inheritance occurs when a child class inherits from multiple parent classes.
Hierarchical inheritance occurs when multiple child classes inherit from the same parent class.
Hybrid inheritance occurs when a combination of more than one type of inheritance is used.

The Diamond Problem

The Diamond Problem occurs when two child classes inherit from a common parent class, resulting in ambiguity.
It is a problem that arises in multiple inheritance.
