Remembering your object-oriented programming

OOP is a vast field of expertise, and its mastery requires not only study but also time spent applying its principles to real-life software development.

With all the foundational information you have learned in this book, it might seem like a mountain you’re just better off not even attempting to climb. However, when you feel that way, take a step back and revisit these key concepts from Chapter 5:

• Classes are blueprints for objects you want to create in code.
• They can contain properties, methods, and events.
• They use constructors to define how they are instantiated.
• Instantiating objects from a class blueprint creates a unique instance of that class.
• Classes are reference types, meaning when the reference is copied, it’s not a new instance.
• Structs are value types, meaning when a struct is copied, a brand-new instance is created.
• Classes can use inheritance to share common...
