Introduction to Interfaces
Welcome to the first lesson in Advanced Programming Concepts! In this lesson, you’ll learn about interfaces, their purpose, and how to use them to achieve abstraction and flexibility in your C# programs. Let’s get started!

What is an Interface?
An interface is a contract that defines a set of methods and properties that a class must implement. It provides no implementation itself but ensures that any class implementing the interface adheres to a specific design.
Example: An interface for a "Vehicle" might define methods like Start() and Stop(), which all vehicles must implement.
Key Point: Interfaces enable you to design flexible and reusable code by separating behavior from implementation.
