C# Conditional Statements – The Complete Guide

Hey there, future C# expert! 👋 Ever wondered how your code makes decisions? Whether it’s checking a user’s login, calculating discounts, or choosing a game mode—conditional statements are everywhere!

In this chapter, you’ll learn how to control the flow of your program using:

✅ If-Else Statements – Making decisions based on conditions.
✅ Switch Case – A cleaner way to handle multiple conditions.

By the end of this, you’ll be able to write smart, efficient, and readable C# programs! 😎

What Will You Learn? 📚

🟢 If-Else Statements (The Basics of Decision Making 🤔)

You’ll start with if-else statements, the building blocks of decision-making in C#. We’ll cover:

✔️ if statement – Runs code only if a condition is true.
✔️ if-else statement – Adds an alternative option when the condition is false.
✔️ else-if statement – Checks multiple conditions.
✔️ Nested if statements – One if inside another for complex decisions.

🔵 Switch Case (For Multiple Choices 🎯)

When you have many conditions to check, switch case makes your code cleaner and easier to read. You’ll learn:

✅ Traditional Switch Statement – The classic way to handle multiple conditions. 🏛️
✅ Switch Expression (C# 8.0+) – A shorter, cleaner way to write switch cases. 📝
✅ Pattern Matching in Switch (C# 9.0+) – A smarter way to handle different types of data. 🎯
✅ Switch with When Clause – Adding extra conditions inside a switch case. 🔍

🟢 Advanced Conditional Statements:

Conditional statements in C# can be enhanced using advanced features that improve efficiency and readability. These features help developers write more concise and optimized code.

✔ && (Logical AND) and || (Logical OR) – Combining conditions.
✔ ?? (Null-Coalescing) and ?. (Null-Conditional) – Handling null values safely.
✔ goto case and goto default – Jumping between switch cases.
✔ Short-Circuit Evaluation – Optimizing performance in condition checks.
