Go by Example 中文：分支结构
|
switch ，方便的条件分支语句。 |
|
package main
|
|
import "fmt"
import "time"
|
|
func main() {
|
|
|
一个基本的 |
i := 2
fmt.Print("write ", i, " as ")
switch i {
case 1:
fmt.Println("one")
case 2:
fmt.Println("two")
case 3:
fmt.Println("three")
}
|
|
在一个 |
switch time.Now().Weekday() {
case time.Saturday, time.Sunday:
fmt.Println("it's the weekend")
default:
fmt.Println("it's a weekday")
}
|
|
不带表达式的 |
t := time.Now()
switch {
case t.Hour() < 12:
fmt.Println("it's before noon")
default:
fmt.Println("it's after noon")
}
}
|
$ go run switch.go
write 2 as two
it's the weekend
it's before noon
|
下一个例子: 数组.
