What is the purpose of access modifiers?
Understand the Problem
The question is asking about the role and function of access modifiers in programming. Access modifiers are keywords in object-oriented programming languages that set the accessibility of classes, methods, and other members. The question aims to identify the correct description of their purpose.
Answer
Access modifiers control the visibility and accessibility of classes and methods, enabling encapsulation and improving code maintainability.
Access modifiers control the visibility and accessibility of classes, methods, and other members within a program. They facilitate encapsulation by restricting access to certain components, thus preventing unintended modifications and improving code maintainability and safety.

More Information
Access modifiers are a key component of object-oriented programming, as they allow developers to control how different parts of a program interact with each other. Different languages may have slightly different access modifiers (e.g. private, protected, public in Java and C#).
Tips
A common mistake is to make everything public, which removes the benefits of encapsulation and can lead to code that is difficult to maintain and debug.
