func main() {
//1）同名字段的使用
var s Student

fmt.Printf("%+v\n", s)
s.Person.name = "god_girl" //显示调用
fmt.Printf("%+v\n", s)
//2) 其他匿名字段
s1 := Student01{Person{"ck_god", 1, 18}, 1, "wz"}
fmt.Printf("%+v\n", s1)
//非结构体类型的匿名成员的操作
fmt.Printf("%s,%c,%d,%d,%s\n",
s1.name, s1.sex, s1.age, s1.int, s1.mystr)
//3)结构体指针类型
s3 := Student02{&Person02{"ck_god", 0, 18}, 1, "bj"}

fmt.Printf("%s,%c,%d\n", s3.name, s3.sex, s3.age)
var s2 Student02
s2.Person02 = new(Person02) //分配空间
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)
}
输出结果如下：
{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,,18
ck 1 20 2 20标签：main ack UNC 指针 ddr add 类型 new 结构体
