go语言初始化内部结构体3中方式

 package main

 import (
     "fmt"
 )

 type User struct {
     Id   int
     Name string
     Age  int
 }

 type Manger struct {
     User
     title string
 }

 func main() {
     m := Manger{User:User{, "ok", }, title:""}  //可以
     m2 := Manger{User{, "ok", }, ""}  //可以
     m3 := Manger{User:User{Id:, Name:"ok", Age:}, title:""}  //可以

     fmt.Println(m)
     fmt.Println(m2)
     fmt.Println(m3)

 }
