Go语言中switch的所有用法

package main

func main() {

    var number int = 5
    switch number {
    case 1:
        println("number = 1")
    case 2:
        println("number = 2")
    case 5:
        println("number = 5")
    }

    //还带这样子的？
    switch number2 := 3; number2 {
    case 0,1,3,4:
        println("number2 = 1")
    case 2:
        println("number2 = 2")
    case 5:
        println("number2 = 5")
    default:
        println("number2 非法")
    }

    switch  {
    case number > 1 && number < 6:
        println("number3 = 1")
        fallthrough//执行完了穿透到下一个case里面继续执行
    case number >=5 && number < 10:
        println("number3 = 10")
    }
}
