The difference between OOP and Prototype languages centralize around the reuse principle (Known as inheritance), its performed via a process of reusing objects (Known as prototype inheritance) in Prototype-based programming languages and via a process of reusing the classes of objects or blueprints of objects (Known as class inheritance).
The decorator is a design pattern that allows behavior to be added to an object in a dynamic way without having to change the implementation of that object. The decorator is considered as Structural design pattern. And an important note is that the decorator follows the Open-Closed Principle.
Decorators in C## can be applied using two methods:
1- Inheriting from a target class and have a setter method to set that target class instance inside the decorator or bypassing the target class as a dependency to the decorator class through the constructor. Then in the overridden functions, we call the target class function with additional decoration. The next UML explains that:
C Language is an evergreen language and is used widely across different industries, This C programming is a must for students and working professionals to become a great Software Engineer especially when they are working in Software Development Domain.

In this article, I am going to share some of the best courses to learn C# or C-Sharp in 2020. These courses are suitable for both beginners and experienced programmers who want to fill gaps in their C# knowledge.
C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.
