let number = 6;

if number % 4 == 0 {
    println!("Number is divisible by 4");
} else if number % 3 == 0 {
    println!("Number is divisible by 3");
} else {
    println!("Number is not divisible by 4 or 3");
}

• Infinite Loop:

struct ImportantExcerpt<'a> {
    part: &'a str,
}

fn main() {
    let novel = String::from("Call me Ishmael. Some years ago...");
    let first_sentence = novel.split('.').next().expect("Could not find a '.'");
    let i = ImportantExcerpt { part: first_sentence };

    println!("Excerpt: {}", i.part);
}

• Lifetime annotations are crucial in defining how long references in structs or functions must live.
• Multiple lifetime parameters can be used to manage complex relationships between references.
