Loops

loop {
code
if ... {break ...}
}

Example

    let mut counter = 0;

    let result = loop {
        counter += 1;
        if counter == 10 {
            break counter * 2;
        }
    };
    println!{"{result}"};
    //Result prints as 20 because that is what follows break (counter * 2)

Nested loop example

       let mut count = 0;
        'counting_up: loop {
            println!("count = {count}");
            let mut remaining = 10;
            loop {
                println!("remaining = {remaining}");
                if remaining == 9 {
                    break;
                }
                if count == 2 {
                    break 'counting_up;
                }
                remaining -= 1;
            }
            count += 1;
        }
        println!("End count = {count}");

While loop example

        let mut number = 3;
        while number !0 = {
            println!("{number}");
            number -= 1;
        }
        println!("HEY!!!");

Example array

    let a = [1,2,3,4,5,6];
    for element in a {
    println!("{element}");
    }
