Go Example--变参函数

package main

import "fmt"

func main()  {
    sum(1,2)
    sum(1,2,3)

    nums := []int{1,2,3,4}
    //nums...将nums切片打平为多个参数
    sum(nums...)
}

//定义变参函数
func sum(nums ...int)  {
    fmt.Println(nums," ")
    total := 0
    for _, num := range nums{
        total +=num
    }
    fmt.Println(total)
}
