Hi all.
I'm studying about *if statement* and *comma ok construction* and I'm not
sure why the piece of code (https://go.dev/play/p/ScFJsih6lwR) bellow does
not work. The compiler says that: *x declared but not used*. However, *x* is
used in the second *if statement *of the *main function*, as you can see.
It is worthy to notice that *x* is just assigned (not declared) in the
first *if *of the *main function*, because I declared it as follows: *var x
int*
func MyFunc() (int, bool) {
return 1, true
}
func main() {
var x int
if x, ok := MyFunc(); !ok {
fmt.Println("Err")
}
fmt.Println(x)
}
Thank you and best regards,
Paulo.
