How to Access Array Elements in Rust - Step by Step Examples

How to Access Array Elements in Rust ?

Answer

To access array elements in Rust, you can use indexing with square brackets.


✐ Examples

1 Accessing Element at Index

In this example,

  1. We declare an array named numbers with integer values.
  2. We access the element at index 2 using indexing numbers[1].
  3. We print the accessed element.

Rust Program

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

Output

2

2 Accessing Elements in a Loop

In this example,

  1. We declare an array named fruits with string values.
  2. We access and print each element of the array using an iterator.

Rust Program

fn main() {
    let fruits = ["Apple", "Banana", "Orange"];
    for fruit in fruits.iter() {
        println!("{}", fruit);
    }
}

Output

Apple
Banana
Orange
