GO struct的匿名字段

package main

import "fmt"

type Skills []string

type Human struct {

    name string

    age int

    weight int

}

type Student struct {

    Human // 匿名字段，那么默认struct就包含了Human的所有字段

    Skills //匿名字段，自定义的类型string slice

    int //内置类型作为匿名字段

    speciality string

}

func main() {

    jane := Student{Human: Human{"Jane", 35, 100}, speciality: "Biology"}

    fmt.Println("Her name is ", jane.name)

    fmt.Println("Her age is ", jane.age)

    fmt.Println("Her weight is ", jane.weight)

    fmt.Println("Her speciality is ", jane.speciality)

    jane.Skills = []string{"anatomy"}

    fmt.Println("Her skills are ", jane.Skills)

    fmt.Println("She acquired two new ones")

    jane.Skills = append(jane.Skills, "physics", "golang")

    fmt.Println("Her skills now are", jane.Skills)

    jane.int = 3

    fmt.Println("Her preferred number is ", jane.int)
