How to create a Three Dimensional Array in Go ?

Answer

To create a Three Dimensional Array in Go, you can use slices of slices of slices.

✐ Examples

1 Creating a 3D Array with Slices

In this example,

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

Go Program

// Creating a 3D Array with Slices
package main

import (
    "fmt"
)

func main() {
    var threeDArray [][][]int
    // Initialize the array
    for i := 0; i < 3; i++ {
        var inner [][]int
        for j := 0; j < 2; j++ {
            inner = append(inner, make([]int, 4))
        }
        threeDArray = append(threeDArray, inner)
    }
    // Modify an element
    threeDArray[1][0][2] = 5
    // Print the array
    fmt.Printf("%v", threeDArray)
}

Output

[[[0 0 0 0] [0 0 0 0]] [[0 0 5 0] [0 0 0 0]] [[0 0 0 0] [0 0 0 0]]]
