Swift嵌套if-else语句用法示例

Swift语言可以帮助你在if-else语句内使用if-else语句。嵌套的if-else语句也可以在Swift的switch语句中使用。

例：

let n1 = 10, n2 = 22, n3 = 25
if n1 >= n2 {
	if n1 >= n3 {
		print("The largest number is ", n1)
	}
	else {
		print("The largest number is ", n3)
	}
}
else {
	if n2 >= n3 {
		print("The largest number is ", n2)
	}
	else {
		print("The largest number is ", n3)
	}
}

输出

The largest number is 25
