C# Object-Oriented Design: Building a Banking Application with Polymorphism

Ready to move beyond basic syntax and write professional, reusable code? Mastering object-oriented programming is the key to building scalable software, and practicing with real-world scenarios is the best way to internalize these concepts. This course guides you through designing and implementing a functional banking system using modern C# principles. You will learn how to structure your code cleanly, making it easy to maintain and expand. What you'll learn: Understand core object-oriented concepts like inheritance, encapsulation, and polymorphism; Design structured class hierarchies with base classes and specialized account types; Implement method overriding and abstract classes to handle distinct banking behaviors; Manage state and data safety using modern C# properties and access modifiers; Apply clean coding practices to handle transactions, interest calculations, and fee structures. The course begins with foundational definitions of object-oriented design before guiding you step-by-step through the structure of a banking application, from base account classes to specific savings and checking logic. This course is designed for beginner C# developers who understand basic syntax and want to learn how to structure real-world applications. No advanced programming experience is required.
