Comment

fn main() {
    // this is how you init a array = [elements]
    let array = [1, 2, 3, 4, 5];
    println!("{:?}", array);
    // this is how you define the type of the array [<type>; <size>] = [elements]
    let array : [i32; 5] = [1, 2, 3, 4, 5];
    println!("{:?}", array);
    // this is how you init a array with a default ::  = [<type and default value>, <size>]
    let array = [1; 5];
    println!("{:?}", array);
    // this is same above array, but hand typed. [<type>; <size>] = [<type and default value>, <size>]
    let array : [i32; 5] = [1; 5];
    println!("{:?}", array);
}
