How to Iterate Over an Array in Reverse Order in Rust - Step by Step Examples

How to Iterate Over an Array in Reverse Order in Rust ?

To iterate over an array in Rust in reverse order, you can use a for loop starting from the last index to the first index.

In this example,

We create an integer array named numbers with some values.
We use a for loop starting from the last index to iterate over each element of the array in reverse order.

fn main() {
    let numbers = [1, 2, 3, 4, 5];
    for i in (0..numbers.len()).rev() {
        println!("{}", numbers[i]);
    }
}

In this example,

We create a string array named fruits with some values.
We use a for loop starting from the last index to iterate over each element of the array in reverse order.

fn main() {
    let fruits = vec!["apple", "banana", "cherry"];
    for i in (0..fruits.len()).rev() {
        println!("{}", fruits[i]);
    }
}

cherry
banana
apple
