How to create a Three Dimensional Array in Rust - Step by Step Examples



How to create a Three Dimensional Array in Rust ?

Answer

To create a Three Dimensional Array in Rust, you can use arrays or vectors.



✐ Examples

1 Creating a 3D Array with Arrays

In this example,

  1. We use arrays of arrays of arrays to create a 3D array.
  2. The first dimension represents the outer array, the second dimension represents the middle array, and the third dimension represents the inner array.

Rust Program

// Creating a 3D Array with Arrays
fn main() {
    let mut three_d_array = [[[0; 4]; 2]; 3];
    // Modify an element
    three_d_array[1][0][2] = 5;
    // Print the array
    for outer in &three_d_array {
        for middle in outer {
            for &value in middle {
                print!("{} ", value);
            }
            println!();
        }
        println!();
    }
}

Output

0 0 0 0 
0 0 5 0 

0 0 0 0 
0 0 0 0 

0 0 0 0 
0 0 0 0
