🔥 In This Tutorial:
━━━━━━━━━━━━━━━━━━━━━━━
0:00 - Introduction
0:06 - Basic If Statement
1:39 - If-Else Statement
3:10 - Else-If Chain (Multiple Conditions)
📚 What You'll Learn:
━━━━━━━━━━━━━━━━━━━━━━━
✅ How to write basic if statements in Rust
✅ Using else to handle the opposite case
✅ Chaining multiple conditions with else-if
✅ How Rust evaluates conditions from top to bottom
✅ Compiling and running Rust programs with rustc
💻 Code Examples:
━━━━━━━━━━━━━━━━━━━━━━━
Example 1 - Basic If:
fn main() {
let number = 5;
if number is greater than 0 {
println!("The number is positive!");
}
}
Example 2 - If-Else:
fn main() {
let number = -3;
if number is greater than 0 {
println!("Positive number!");
} else {
println!("Not a positive number!");
}
}
Example 3 - Else-If Chain:
fn main() {
let number = 0;
if number is greater than 0 {
println!("Positive!");
} else if number is less than 0 {
println!("Negative!");
} else {
println!("Zero!");
}
}
🦀 Key Takeaways:
━━━━━━━━━━━━━━━━━━━━━━━
• Rust if statements don't need parentheses around conditions
• Only ONE block executes in an if-else-if chain
• Conditions are checked from top to bottom
• The else block catches everything else
📌 Prerequisites:
━━━━━━━━━━━━━━━━━━━━━━━
• Rust installed (rustc --version to verify)
• Basic understanding of Rust syntax
• Watch our "Getting Started with Rust" video first!
