How to Declare an Integer Array in Rust

How to Declare an Integer Array in Rust ?

To declare an integer array in Rust, you can use array notation or the Vec container.

In this example,

We declare an integer array named numbers with predefined values using array notation.
We print the array to demonstrate the initialization.

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

Integer Array: [1, 2, 3, 4, 5]

In this example,

fn main() {
    let empty_array: Vec<i32> = Vec::new();
    println!("Empty Integer Array: {:?}", empty_array);
}

Empty Integer Array: []

In this tutorial, we learned How to Declare an Integer Array in Rust language with well detailed examples.
