结构属性取值

package main

import (
    "fmt"
    "reflect"
)

type person struct {
    name string
    age  int
}

func main() {
    p := person{name: "Tom", age: 12}
    fmt.Println(reflect.TypeOf(p))
    fmt.Println(p.name)
    fmt.Println((&p).name)  
    // fmt.Println(p->name) // 失败：无效操作符
    // fmt.Println((*p).name)  // 失败：错误指针变量
}
