Did you know? The name "Cool" is a tribute to the original code name of C# inside Microsoft in 2000, which stood for "C-like Object Oriented Language". This repository documents my journey in mastering it.

A robust grade calculation tool that focuses on clean code principles, strict input validation, and modern C# syntax.

Key Concepts Applied:

• Modern Switch Expressions: Using C# 8.0+ syntax for cleaner logic flow.
• Pattern Matching: Implementing logical patterns (e.g., > 100 or < 0) directly within switch statements.
• Defensive Programming: Using int.TryParse to prevent runtime crashes from invalid user inputs.
• String Manipulation: utilizing Split with StringSplitOptions.RemoveEmptyEntries to handle edge cases like extra whitespace.
• Control Flow: Efficient use of foreach loops and conditional breaks.
