Yes thank you Andrey,
I noticed this shortly after sending the example in the email. I redid the
procedure on the code below which is not optimized by the Go compiler, and
I get the same conclusions as before, you can check.
Best,
Karolina
*switch-go-improved/main.go----------------------------------------------package
mainimport ( "fmt" "os" "strconv")func main() { // this is so
that the Go compiler doesn't optimize drasticvally the code if
os.Args[1] == "" { fmt.Println("Please provide a number (1, 5, 10,
or other)") os.Exit(1) } x, err := strconv.Atoi(os.Args[1])
if err != nil { fmt.Println("Invalid number") os.Exit(1)
} switch x { case 1: fmt.Println("One") case 5:
fmt.Println("Five") case 10: fmt.Println("Ten") default:
fmt.Println("Other") }}*
*----------------------------------------------*
