After his conversation with Sophie, Mark decided to write to his mentor David to reflect on what he had learned.

Hi David,

I just wanted to share a quick update. After sitting in on a recent code review, I finally feel like I'm starting to understand some key programming concepts.

Sophie explained terms like polymorphism, encapsulation, inheritance, and abstraction. For example, I saw how encapsulation helps with keeping details hidden and making the code easier to work with. I also noticed polymorphism in a method that changes behavior depending on the input.

I tried writing a small class using these ideas — focusing on clean code structure, reusing properties and methods, and simplifying functionality.

Does it mean I'm on the right track if I can explain these terms and apply them in a simple project?

Thanks for explaining these things over time. I appreciate the explanations and all your support.

Best,

Mark
