How to Iterate over a Two Dimensional Array in Rust ?

Answer

To iterate over a Two Dimensional Array in Rust, you can use nested loops.

✐ Examples

1 Iterating over a 2D Array of Integers

In this example,

We declare and initialize a 2D array of integers named matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

Rust Program

fn main() {
    let matrix = [[0, 1, 2], [1, 2, 3], [2, 3, 4]];
    for row in &matrix {
        for &element in row {
            print!("{} ", element);
        }
        println!();
    }
}

Output

0 1 2 
1 2 3 
2 3 4

2 Iterating over a 2D Array of Characters

In this example,

We declare and initialize a 2D array of characters named matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each character of the array.

Rust Program

fn main() {
    let matrix = [['a', 'b'], ['c', 'd']];
    for row in &matrix {
        for &element in row {
            print!("{} ", element);
        }
        println!();
    }
}

Output

a b 
c d
