函数多个形参

package main

import "fmt"

func test(a int, agrs ...int) {
    fmt.Println("a=", a)
    fmt.Println("len(agrs)=", len(agrs))
    for i := 0; i < len(agrs); i++ {
        fmt.Printf("agrs[%d]=%d\t", i, agrs[i])
    }
}

func main() {
    test(1, 2, 3, 4)
}
//输出
/*
a= 1
len(agrs)= 3
agrs[0]=2       agrs[1]=3       agrs[2]=4
*/
