How to calculate the next multiple of 10 in Rust

Answer 1

fn next_multiple_of_10(n: i32) -> i32 {
    if n % 10 == 0 {
        n + 10
    } else {
        n + (10 - n % 10)
    }
}

fn main() {
    let nums = [23, 10, 0, 1841];

    for &n in nums.iter() {
        println!("{}", next_multiple_of_10(n));
    }
}
