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

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 -=
