Hi there.
I try to create a function for calculating square area and perimeter both.

func square(a int) (int, int) {
sq := a * a
per := 4 * a
return sq, per
}

But, it is not working. Can anybody help?

Hi there @akutsenko, welcome to the forums!

What exactly isn’t working? What is the expected result?
What happens when you call your function?

Hi. Thanx 4 your feedback.

I rewriting a function as:

func square(a int) (int, int) {
var sq, per int
sq = a * a
per = 4 * a
return sq, per
}

And ran it:

func main() {
fmt.Println(“Our square area and perimetr is:”, square(13))
}

I’ll make a mistake: multiple-value square() in single-value context

If i calling this functions just:

func main() {
fmt.Println(square(13))
}

Everything is ok!

i found this fix:

func main() {
a, b := square(13)
fmt.Println(“Our square area and perimetr is:”, a, b)
}
