Rust Arrays & Vectors Tutorial | Fixed vs Dynamic Collections for Beginners

🦀 Learn Rust Arrays & Vectors - Essential Collections for Every Rust Programmer! In this beginner-friendly tutorial, you'll master the difference between fixed-size arrays and dynamic vectors in Rust. We'll write real code in nvim with syntax highlighting and see the output in the terminal. ⏱️ What You'll Learn: 0:00 - Introduction 0:12 - Arrays: Fixed-Size Collections 2:51 - Vectors: Dynamic Collections 5:35 - Iterating Over Collections with For Loops 8:16 - Recap & Next Steps 📚 Topics Covered: • Creating arrays with let arr = [1, 2, 3, 4, 5] • Accessing elements with arr[0] (zero-indexed) • Getting array length with arr.len() • Creating vectors with Vec::new() • Adding elements with v.push(item) • Iterating with for item in collection { } • Calculating totals and averages 💻 Code Examples: ARRAYS: fn main() { let numbers = [10, 20, 30, 40, 50]; println!("First: {}", numbers[0]); println!("Length: {}", numbers.len()); } VECTORS: fn main() { let mut fruits = Vec::new(); fruits.push("Apple"); fruits.push("Banana"); println!("Fruits: {:?}", fruits); } ITERATION: fn main() { let scores = [85, 92, 78, 95, 88]; for score in scores { println!("Score: {}", score); } } 🔑 Key Differences: • Arrays: Fixed size, known at compile time • Vectors: Dynamic size, can grow with push() • Both: Zero-indexed, iterable with for loops 📌 Subscribe for more Rust tutorials! #Rust #RustLang #Programming #LearnRust #CodingTutorial #Arrays #Vectors #BeginnerProgramming
