Master the art of building robust C# classes through hands-on drills and engaging theory. Explore constructors, encapsulation, access modifiers, static classes, and more, with real-world inspired challenges.

Dive into the world of constructors in C#. Learn how to initialize objects, use constructor overloading, and apply best practices for flexible class instantiation.

Explore the principles of class design, encapsulation, and how to protect and organize data using access modifiers.

Learn how to use static classes and members for shared data and utility functionality in C#.

Delve into advanced class construction topics: composition vs inheritance, and refactoring structs into classes for more complex scenarios.
