What Makes Good Code? – Should Every Class Have An Interface? Pt 1

What's An Interface? I mentioned in the first post of this series that I'll likely be referring to C# in most of these posts. I think the concept of an interface in C# extends to other languages--sometimes by a different name--so the discussion here may still be applicable. Some examples in C++, Java,¬†and Python to get you going for comparisons. From MSDN: An interface contains definitions for a group of related functionalities that a class or a struct can implement. By using interfaces, you can, for example, include behavior from multiple sources in a class. That capability is important in C# because the language doesn't support multiple inheritance of classes. In addition, you must use an interface if you want to simulate inheritance for structs, because they can't actually inherit from another struct or class. It's also important to note…
