Swapping of two numbers in Go Programming

func main() {

	var a int = 3
    var b int = 6

	fmt.Println("The value of a before swap is " + strconv.Itoa(a))
	fmt.Println("The value of b before swap is " + strconv.Itoa(b))
	
    // Swapping of two numbers using temp variable
	var temp int = a
    a = b
    b = temp

	fmt.Println("The value of a after swap is " + strconv.Itoa(a))
	fmt.Println("The value of b after swap is " + strconv.Itoa(b))	
}
