       s1
       x string
}
type s4 struct {
       *s1
       x string
}
func main() {
       
       x2 := s2{}
       x2.s.a = "1"
       x2.x = "2"

       x3 := s3{}
       x3.a = "1"
       x3.s1.a = "2"
       x3.x = "3"
       fmt.Println(x3.a, x3.s1.a)

       x4 := s4{
              &s1{},
              "3",
       }
       x4.a = "1"
       x4.s1.a = "2"
       x4.x = "3"
       fmt.Println(x4.a, x4.s1.a)

}

用哪种看自己喜欢了
