rust iterate over array

let a = [1, 2, 3, 4, 5];

for element in a.iter() {
    println!("{}", element);
}

This will print the elements of the array a on separate lines.

You can also use a for loop with an enumerated iterator to get the index and value of each element:

for (i, element) in a.iter().enumerate() {
    println!("The value at index {} is {}", i, element);
}

You can also use a while loop to iterate over the elements of an array, like this:

let mut i = 0;
while i < a.len() {
    println!("{}", a[i]);
    i += 1;
}
