Access Modifiers

Access modifiers are keywords used in programming to define the visibility and accessibility of class members, such as attributes and methods. They play a crucial role in encapsulation, which helps protect sensitive data and maintain the integrity of the code. In Object-Oriented Programming (OOP), access modifiers are essential for writing robust and maintainable code.

In C++, there are three primary access modifiers:

Public: Members declared as public can be accessed from anywhere in the program. They are typically used for methods that allow interaction with private data.
Protected: Members declared as protected are accessible within the defining class and its derived classes. This is particularly useful for inheritance, allowing child classes to access and reuse members from the parent class.
Private: Members declared as private can only be accessed within the defining class. This helps hide implementation details and prevents unauthorized access or modification of sensitive data ¹.

If you have further questions about access modifiers or their implementation, feel free to ask!
