package main

import "fmt"

type Person struct {

	Id   int

	Name string

	Sex  byte

}

type Student struct {

	Person

	Hobby string

}

func (s Person) PrintValue() {

	fmt.Println("该方法receiver is person")

}

func (s *Person) Printpointer() {

	s.Name = "st"

	fmt.Println("该方法receiver is *person")

}

func main() {

	s1 := Student{Person{1, "steven", 'm'}, "running"}

	s1.PrintValue() //继承person的方法

　　　　　s1.Printpointer()//自动转换类型

	var s2 *Student

	s2 = new(Student)

	s2.Printpointer()

	fmt.Println(s2.Name)//st
