internal: Members declared as internal are accessible within the same assembly.This access modifier is useful when you want to provide access to members for subclasses, but not for the rest of the code. protected: Members declared as protected are accessible within the same class and any derived classes.They have the most restriction on their visibility and are used to encapsulate implementation details. private: Members declared as private are only accessible within the same class.They have the least restriction on their visibility. ![]() public: Members declared as public are accessible from any part of the code.There are five different access modifiers available in C#: They help to define the scope of the members and enforce encapsulation. What is the purpose of using access modifiers in C#, and can you provide examples of the different access modifiers available? AnswerĪccess modifiers in C# are used to control the visibility and accessibility of class members (properties, methods, and fields). In OOP, abstraction is achieved through the use of abstract classes and interfaces, which define the common properties and methods that a group of related classes should have. Abstraction: Abstraction is the process of simplifying complex systems by breaking them down into smaller, more manageable parts.This enables a single function or method to operate on multiple types of objects, making the code more flexible and extensible. Polymorphism: Polymorphism allows objects of different classes to be treated as objects of a common superclass.This helps to promote code reusability and maintainability by allowing new classes (derived classes) to reuse the functionality of existing classes without modifying them. Inheritance: Inheritance is the ability of a class to inherit properties and methods from a parent class (base class).This helps to hide the implementation details from the outside world, allowing access only through a well-defined interface. Encapsulation: Encapsulation is the process of bundling the data and the methods (functions) that operate on the data within a single unit called a class.The four fundamental principles of Object-Oriented Programming (OOP) in C# are: ![]() What are the four fundamental principles of Object-Oriented Programming (OOP) in C#?
