How to Initialize an Array in Go - Step by Step Examples

How to Initialize an Array in Go ?

Answer

To initialize an array in Go, you can use array literals or the make() function. In this tutorial, we will go through examples on how to use array literals or the make() function to create integer arrays, string arrays, etc.

✐ Examples

1 Initialize Array using Array Literals

In this example,

We initialize an array named numbers using array literals with integer values.
This creates an array of integers in Go.
We print the array elements to the console.

Go Program

package main
import "fmt"
func main() {
    numbers := [5]int{1, 2, 3, 4, 5}
    fmt.Println(numbers)
}

Output

[1 2 3 4 5]

2 Initialize Array using make() Function

In this example,

We initialize an array named fruits using the make() function with string values.
This creates an array of strings in Go.
We print the array elements to the console.

Go Program

package main
import "fmt"
func main() {
    fruits := make([]string, 3)
    fruits[0] = "Apple"
    fruits[1] = "Banana"
    fruits[2] = "Orange"
    fmt.Println(fruits)
}

Output

[Apple Banana Orange]
