[GO]结构体类型添加方法

package main

import "fmt"

type Person struct {
    name string
    sex byte
    age int
}
//带有接收者的函数叫方法
func (tmp Person) PrintInfo()  {
    fmt.Println("person = ", tmp)
}

func (tmp *Person) SetInfo(n string, s byte, a int)  {
    tmp.name = n
    tmp.sex = s
    tmp.age = a
    fmt.Println("set info = ", *tmp)
}

func main() {
    p := Person{"baylor", ‘m‘, 18}
    p.PrintInfo()
    var s Person
    (&s).SetInfo("mike", ‘f‘, 18)
    s.PrintInfo()
}

person =  {baylor 109 18}
set info =  {mike 102 18}
person =  {mike 102 18}
