package main

import (
    "fmt"
    "log"
)

func main() {
    n := 2

    // Reference the adress from the variable.
    nPtr := &n

    // Print out the address.
    fmt.Println(nPtr)

    // Dereference the pointer to get the value.
    if !(*nPtr == 2) {
        log.Fatal("Wrong value")
    }
}
