invalid array access example is no longer accurate

[dhiltonp]

https://doc.rust-lang.org/book/ch03-02-data-types.html#invalid-array-element-access

The code sample:

fn main() {
    let a = [1, 2, 3, 4, 5];
    let index = 10;

    let element = a[index];

    println!("The value of element is: {}", element);
}

Does not compile with cargo run (cargo 1.45.1 (f242df6ed 2020-07-22)).

This is good, but means the example is out of date.

I think this should be opened in rust-lang/book and not here

This is a duplicate of rust-lang/book#2417, should be closed
