What are access modifiers?

What are access modifiers in programming?

Access modifiers are keywords used in object-oriented programming to set the visibility of classes, methods, and variables.

Can you explain the different types of access modifiers?

Sure! The main types are public, private, and protected. Public members are accessible from anywhere, private members are only accessible within the class, and protected members are accessible within the class and its subclasses.

What is the purpose of using private access modifiers?

Private access modifiers help encapsulate data, ensuring that it cannot be accessed directly from outside the class, which enhances security and maintainability.

Are there any other access modifiers I should know about?

Yes, there's also the 'internal' modifier in languages like C#, which restricts access to the same assembly, and 'protected internal' which combines both protected and internal access.
