golang for range 引用注意的問題

 

package main

import "fmt"

type Student struct {
	Name string
	Age  int
}

func main() {
	data := make([]*Student, 0)

	src := []Student{
		Student{Name: "allen", Age: 30},
		Student{Name: "tom", Age: 33},
	}

	for _, m := range src {
		data = append(data, &m)
	}

	for _, s := range data {
		fmt.Println(*s)
	}

}

 

輸出結果:

{tom 33}

{tom 33}

不是:

{allen 30}

{tom 33}
