package main

    "fmt"

func main() {
    var ar = [3]int{1, 2, 3}
    br := &ar

    fmt.Println(ar)
    fmt.Println(br)
    ar[1] = 42
    fmt.Println(ar)
    fmt.Println(br)

    fmt.Println(ar[1])
    fmt.Println(br[1])

This way br is a poiner to ar so they refer to the same data in memory. Even though br is a pointer we can still access elements in the same way as in the original array. We'll discuss pointers in depth later on.
