我正在尝试从下面的if语句转换为switch语句,但是我一直在出错。
let meal = "breakfast"
if meal == "breakfast" {
print("Good morning!")
} else if meal == "lunch" {
print("Good afternoon!")
} else if meal == "dinner" {
print("Good evening!")
} else {
print("Hello!")
}
这是我的switch声明:
switch meal {
let meal = "breakfast"
case 1:
print("Good morning!”)
case 2:
print("Good afternoon!")
case 3:
print("Good evening!")
}
答案 0 :(得分:1)
let meal = "breakfast"
switch meal {
case "breakfast":
print("Good morning")
case "lunch":
print("Good afternoon!")
case "dinner":
print("Good evening!")
default:
print("default case")
}
将此开关块放入您的代码中:)
