struct 。 看一个例子，让上面说的这些更具体化 看到Student访问属性age和name的时候，就像访问自己所有用的字段一样，匿名字段就是这样，能够 实现字段的继承。student还能访问Human这个字段作为字段名。请看下面的代码。 tb_Older, tb_diff := Older(tom, bob) tp_Older, tp_diff := Older(tom, paul) } package main import "fmt" type Human struct { name string age int weight int } type Student struct { Human // 匿名字段，那么默认Student就包含了Human的所有字段 speciality string } func func main() { // 初始化一个学生 mark := Student{Human{"Mark", 25, 120}, "Computer Science"} // 访问相应的字段 fmt.Println("His name is ", mark.name) fmt.Println("His age is ", mark.age) fmt

"fmt" type Human struct { name string age int weight int } type Student struct { Human // embedded field, it means Student struct includes all fields that Human has. specialty string } func main() { // instantiate and initialize a student mark := Student{Human{"Mark", 25, 120}, "Computer Science"} // access fields fmt.Println("His name is ", mark mark.weight) } Figure 2.7 Embedding in Student and Human We see that we can access the age and name fields in Student just like we can in Human. This is how embedded fields work. It's very cool,

让我们来看一个例子，让上面说的这些更具体化 package main import "fmt" type Human struct { name string age int weight int } type Student struct { Human // 匿名字段，那么默认Student就包含了Human的所有字段 speciality string } func main() main() { // 我们初始化一个学生 mark := Student{Human{"Mark", 25, 120}, "Computer Science"} // 我们访问相应的字段 fmt.Println("His name is ", mark.name) fmt.Println("His age is ", mark.age) fmt.Println("His Student和Human的方法继承 我们看到Student访问属性age和name的时候，就像访问自己所有用的字段一样，对，匿名字段就是这样，能够实现字 段的继承。是不是很酷啊？还有比这个更酷的呢，那就是student还能访问Human这个字段作为字段名。请看下面的代 码，是不是更酷了。 mark.Human = Human{"Marcus", 55, 220} mark.Human.age -=
