• There are two types of threads: user-level threads and kernel-level threads.

• User-level threads are managed by the application and are faster to create and switch between, but can't take advantage of multiple processors.

• Kernel-level threads are managed by the operating system and can take advantage of multiple processors, but are s...read more

Inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class.

• Inheritance allows code reuse and promotes code organization.

• There are different types of inheritance: single, multiple, multilevel, hierarchical, and hybrid.

• Single inheritance involves a class inheriting from a single base class.

• Multiple inheritance involves a class inheriting from multiple base...read more

Polymorphism is the ability of an object to take on many forms. It has two types: compile-time and runtime polymorphism.

• Compile-time polymorphism is achieved through function overloading and operator overloading.

• Runtime polymorphism is achieved through virtual functions and function overriding.

• Polymorphism allows for code reusability and flexibility in object-oriented programming.

• Example of compile-time polymorphism: f...read more

Encapsulation is the process of hiding implementation details and providing a public interface for accessing the functionality.

• Encapsulation helps in achieving data abstraction and information hiding

• It prevents unauthorized access to the internal details of an object

• It allows for easy modification of implementation without affecting the external code

• Example: A class with private variables and public methods

• Example: A b...read more
