// code_016_struct_anonymous_field2 project main.gopackage mainimport ( "fmt")type Person struct { name string sex byte age int}type Student struct { Person id int addr string name string //同名欄位}type mystr string //自訂類型type Student01 struct { Person int mystr}type Person02 struct { name string sex byte age int}type Student02 struct { *Person02 //匿名欄位，結構體指標 id int addr string}func main() { //1）同名欄位的使用 var s Student s.name = "ck_god" //預設給最外層的成員賦值 fmt.Printf("%+v\n", s) s.Person.name = "god_girl" //顯示調用 fmt.Printf("%+v\n", s) //2) 其他匿名欄位 s1 := Student01{Person{"ck_god", 1, 18}, 1, "wz"} fmt.Printf("%+v\n", s1) //非結構體類型的匿名成員的操作 fmt.Printf("%s,%c,%d,%d,%s\n", s1.name, s1.sex, s1.age, s1.int, s1.mystr) //3)結構體指標類型 s3 := Student02{&Person02{"ck_god", 0, 18}, 1, "bj"} fmt.Printf("%+v\n", s3) fmt.Printf("%s,%c,%d\n", s3.name, s3.sex, s3.age) var s2 Student02 s2.Person02 = new(Person02) //分配空間 s2.name = "ck" s2.sex = 1 s2.age = 20 s2.id = 2 s2.addr = "sz" fmt.Println(s2.name, s2.sex, s2.age, s2.id, s2.age)}

輸出結果如下：

{Person:{name: sex:0 age:0} id:0 addr: name:ck_god}{Person:{name:god_girl sex:0 age:0} id:0 addr: name:ck_god}{Person:{name:ck_god sex:1 age:18} int:1 mystr:wz}ck_god,,18,1,wz{Person02:0xc000004480 id:1 addr:bj}ck_god,,18ck 1 20 2  20
