How to Declare a String Array in Rust - Step by Step Examples

How to Declare a String Array in Rust ?

To declare a string array in Rust, you can use array initialization syntax or create a Vec (vector) of strings.

In this example,

We declare a string array named string_array using array initialization syntax with predefined string values.
We print the array elements to the console to demonstrate the initialization.

fn main() {
    let string_array = ["Hello", "World", "Rust"];
    for str in &string_array {
        println!("{}", str);
    }
}

Hello
World
Rust

In this example,

fn main() {
    let empty_string_array: Vec<&str> = Vec::new();
    for str in &empty_string_array {
        println!("{}", str);
    }
}

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