Rust Loops Tutorial | loop while for for Beginners (2024)

Learn all three types of loops in Rust with a relaxed, beginner-friendly pace! This tutorial covers loop with break, while loops with conditions, and for loops with ranges. 🔥 In This Tutorial: ━━━━━━━━━━━━━━━━━━━━━━━ 0:00 - Introduction 0:11 - Basic loop with break 2:30 - While Loop (Countdown Timer) 4:53 - For Loop with Range 📚 What You'll Learn: ━━━━━━━━━━━━━━━━━━━━━━━ ✅ The infinite 'loop' keyword and how to break out ✅ While loops that check conditions each iteration ✅ For loops with range syntax (1..6 vs 1..=5) ✅ Using 'mut' for mutable variables ✅ When to use each loop type 💻 Code Examples: ━━━━━━━━━━━━━━━━━━━━━━━ Example 1 - Basic Loop with Break: fn main() { let mut count = 0; loop { count = count + 1; println!("Count is: {}", count); if count == 5 { break; } } } Example 2 - While Loop Countdown: fn main() { let mut seconds = 5; while seconds is greater than 0 { println!("{} seconds remaining...", seconds); seconds = seconds - 1; } println!("Liftoff!"); } Example 3 - For Loop with Range: fn main() { for number in 1..6 { println!("Number: {}", number); } } // Note: 1..6 gives 1,2,3,4,5 (6 is excluded) // Use 1..=5 for inclusive range 🦀 Key Takeaways: ━━━━━━━━━━━━━━━━━━━━━━━ • loop runs forever until break is called • while checks a condition before each iteration • for is best for iterating over ranges • 1..6 excludes the end, 1..=5 includes it • Use 'mut' when you need to change a variable 📌 Prerequisites: ━━━━━━━━━━━━━━━━━━━━━━━ • Rust installed (rustc --version) • Basic understanding of Rust syntax • Watch our previous Rust tutorials! 👍 Like, Subscribe & Share for more Rust tutorials! #Rust #RustLang #Programming #Loops #ForLoop #WhileLoop #Coding #Tutorial #LearnRust #Beginner #rustlang2024
