How to Initialize an Array in Rust

How to Initialize an Array in Rust ?

To initialize an array in Rust, you can use array literals or the array macro.

In this example,

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

1 2 3 4 5

In this example,

We declare an array named fruits with character values using the array! macro.
This creates a character array in Rust.
We print the array elements.

fn main() {
    let fruits = array!['A', 'p', 'p', 'l', 'e'];
    for fruit in fruits.iter() {
        println!("{} ", fruit);
    }
}

A p p l e
