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

How to Iterate Over an Array in Rust ?

To iterate over an array in Rust, you can use iterators or a for loop.

In this example,

We create an integer array named numbers with some values.
We use a for loop to iterate over each element of the array and print the elements.

fn main() {
    let numbers = [1, 2, 3, 4, 5];
    for num in &numbers {
        println!("{}", num);
    }
}

In this example,

We create a string array named fruits with some values.
We use an iterator to iterate over each element of the array and print the elements.

fn main() {
    let fruits = ["apple", "banana", "cherry"];
    for fruit in fruits.iter() {
        println!("{}", fruit);
    }
}

apple
banana
cherry
