修改结构体值时，重复的参数错误，s就是重复的祸根

package main

import "fmt"

type SS struct {
   S string
   I int
}

func (s *SS) Test(i int)  {
   s.I=i

}
func (s *SS) TestString(s string)  {
   s.S=s

}

func main() {
   s:=&SS{S: "test"}
   s.Test(100)
   s.TestString("cheyunhua")
   fmt.Println(s.S)

}

# command-line-arguments
.\test16.go:14:25: duplicate argument s
.\test16.go:15:3: s.S undefined (type string has no field or method S)
