C# Object-Oriented Programming: Student Marks Calculator

Ready to transition from writing simple scripts to building structured, reusable code in C#? Mastering classes and objects is the essential first step toward becoming a proficient software developer. This text-based course guides you through the core principles of Object-Oriented Programming (OOP) using a practical student marks calculator project. You will understand how to model real-world data, secure your fields with encapsulation, and write clean, maintainable C# code. What you'll learn: Understand foundational OOP terminology including classes, objects, and encapsulation; Create robust C# classes with private fields and modern auto-implemented properties; Initialize object data efficiently using custom constructors; Write methods to retrieve student marks and calculate averages using expression-bodied members; Apply basic validation to protect your class data from invalid values; Test your logic using simple console outputs and structured assertions. The course starts with essential terminology and the theory behind objects and classes. You will then progress through step-by-step written explanations and code snippets to build, refine, and test your student marks calculator using modern C# conventions. This course is designed for beginner programmers and those new to OOP in C#. No prior object-oriented experience is required. Start reading today to build a solid foundation in C# object-oriented programming.
