不加入标签，只能break swtich

package main

func main() {
	i := 10
	for {
		i--
		switch i {
		case 1:
			break 
		}
		if i == -10 {
			break
		}
		println(i)
	}
}

加入标签才能break 外面的循环

package main

func main() {
	i := 10
OuterLoop:
	for {
		i--
		switch i {
		case 1:
			break OuterLoop
		}
		if i == -10 {
			break
		}
		println(i)
	}
}
