Arrays

Arrays have a fixed length that can store items of the same type. They are denoted by [T, N], where T is any type and N is the number of elements in array. The size of the array cannot be a variable, but has to be a literal usize value:

// arrays.rs

fn main() { 
    let numbers: [u8; 10] = [1, 2, 3, 4, 5, 7, 8, 9, 10, 11]; 
    let floats = [0.1f64, 0.2, 0.3]; 

    println!("Number: {}", numbers[5]);
    println!("Float: {}", floats[2]);
}

In the preceding code, we declared an array, numbers, which contains 10 elements for which we specified the type on the left. In the second array, floats, we specified the type as a suffix to the first item of the array, that is, 0.1f64. This is another way to specify types. Next, let's look at tuples.
