Arrays are ordered, meaning each element has a numbered position known as its index. We access an array element by referring to its index number.
Arrays use zero-based indexing, so the first element in an array has an index of 0, the second element has an index of 1, etc.
We're using bracket notation ([]) with the index after the name of the array to access the element:
let animals = vec!["cat", "dog", "parrot"];
println!("{}", animals[0]); // Output: "cat"
println!("{}", animals[1]); // Output: "dog"
println!("{}", animals[2]); // Output: "parrot"
