How to Initialize an Array in Rust - Step by Step Examples
How to Initialize an Array in Rust ?
Answer
To initialize an array in Rust, you can use array literals or the array macro.
✐ Examples
1 Initialize Integer Array using Array Literals
In this example,
- We declare an array named
numbers
with integer values using array literals. - This creates an integer array in Rust.
- We print the array elements.
Rust Program
fn main() {
let numbers = [1, 2, 3, 4, 5];
for number in &numbers {
println!("{} ", number);
}
}
Output
1 2 3 4 5
2 Initialize Character Array using array Macro
In this example,
- We declare an array named
fruits
with character values using thearray!
macro. - This creates a character array in Rust.
- We print the array elements.
Rust Program
fn main() {
let fruits = array!['A', 'p', 'p', 'l', 'e'];
for fruit in fruits.iter() {
println!("{} ", fruit);
}
}
Output
A p p l e
