[golang]golang 语法糖'...'三个点的用法

package main

import "fmt"

func Greeting(prefix string, who ...string) {

    fmt.Println(prefix)
    for _, name := range who {
        fmt.Println(name)
    }

}
func main() {

    Greeting("Hello:", "tom", "mike", "jesse")

}

输出结果：

Hello:

tom

mike

jesse

func test1(args ...string) { //可以接受任意个string参数
    for _, v:= range args{
        fmt.Println(v)
    }
}

func main(){
var strss= []string{
        "qwr",
        "234",
        "yui",
        "cvbc",
    }
    test1(strss...) //切片被打散传入
}

结果
qwr
234
yui
cvbc
