Just as in life, a C# class can be created in the image of another class, sharing its member variables and methods, but able to define its unique data. In OOP, we refer to this as inheritance, and it's a powerful way of creating related classes without having to repeat code. Take the soda example again—there are generic sodas on the market that have all the same basic properties, and then there are special sodas.
