Arrays

• Array items are fixed in size.
• Array items have the same type.
• Fast

fn main(){
    let my_array = ["a" ; 40];
    println!("{:?}" , my_array);
}

Array Slicing

• use a ref

fn main(){
    let my_arr = [1,2,3,4,5,6,7,8,9,10];

    let three_to_five = &my_arr[2..5];
    let start_at_two = &my_arr[1..];
    println!("three to five {:?} , start at two {:?}" , three_to_five , start_at_two);
}
