if loop in go code example

Example 1: if statements in go

a := 4
b := 6
if a + b == 10 {
  fmt.Println("a + b is equal to 10!")
} else {
  fmt.Println("a + b does not equal 10...")
}

Example 2: go if

func sqrt(x float64) string {
	if x < 0 {
		return sqrt(-x) + "i"
	}
	return fmt.Sprint(math.Sqrt(x))
}

func main() {
	fmt.Println(sqrt(2), sqrt(-4))
}
