In some instances, we will want to loop through an array using indices.
The indices of an array meals are all the integer values from 0 to meals.len() - 1, so we can iterate over them using an index variable i:
let meals = vec!["pancakes", "pasta", "pizza", "avocado"];
for i in 0..meals.len() {
println!("Meal number {} is {}.", i + 1, meals[i]);
}
The output of this code is:
Meal number 1 is pancakes.
Meal number 2 is pasta.
Meal number 3 is pizza.
Meal number 4 is avocado.
