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

We iterate through the array using a for loop.
For each index, we access and print the element.

Go Program

package main
import "fmt"
func main() {
    fruits := [3]string{"Apple", "Banana", "Orange"}
    for i := 0; i < len(fruits); i++ {
        fmt.Println(fruits[i])
    }
