### 概述 結構體默認是值傳遞,可以加上&使用引用傳遞 ### 實例 #### 值傳遞 ~~~ type Student struct { id int name string } func change(obj Student) { obj.name = "米蘭" fmt.Println(obj) } func main() { stu := Student{} stu.id = 1 stu.name = "jack" change(stu) fmt.Println(stu) } ~~~ ~~~ {1 米蘭} {1 jack} ~~~ #### 引用傳遞 ~~~ type Student struct { id int name string } func change(p *Student) { p.name = "米蘭" fmt.Println(p) } func main() { stu := Student{} stu.id = 1 stu.name = "jack" change(&stu) fmt.Println(stu) } ~~~ ~~~ &{1 米蘭} {1 米蘭} ~~~
