My .Net Developer Journey - Day 3 | Arrays, Collections & Clean Iteration

Описание: Welcome to Day 3 of my .NET Developer training journey 🚀

In this video, I focus on one of the most important C# fundamentals: working with collections of data using arrays and List. Understanding how and when to use each is essential for writing efficient, maintainable .NET applications.

📌 What this Day 3 session covers:

📦 Arrays in C#
• What arrays are and why we need them
• Declaring, initializing, accessing, and updating arrays
• Understanding zero-based indexing
• Iterating through arrays using for and foreach loops

🔁 foreach Loop
• Clean and readable iteration for arrays and collections
• When foreach is preferable over for loops

📋 Collections with List
• Why arrays are fixed-size
• Using List for dynamic data
• Adding items and iterating through lists
• Understanding how List works internally

🧪 Hands-On Practice
• Calculating averages using arrays
• Finding the maximum value with a method
• Building a simple to-do list using List

🧠 Critical Thinking Focus
• Why arrays are fixed-size by design
• When to use arrays vs List
• Performance vs flexibility trade-offs

💡 Key Focus:
Choosing the right data structure based on performance, memory, and use case — not just convenience.
