九、struct

定义自己的类型

type foo int

struct

 1 package main
 2 
 3 import "fmt"
 4 
 5 type Skills []string
 6 
 7 type Human struct {
 8     name   string
 9     age    int
10     weight int
11 }
12 
13 type Student struct {
14     Human      // 匿名字段，struct
15     Skills     // 匿名字段，自定义的类型string slice
16     int        // 内置类型作为匿名字段
17     speciality string
18 }
19 
20 func main() {
21     // 初始化学生Jane
22     jane := Student{Human: Human{"Jane", 35, 100}, speciality: "Biology"}
23     // 现在我们来访问相应的字段
24     fmt.Println("Her name is ", jane.name)
25     fmt.Println("Her age is ", jane.age)
26     fmt.Println("Her weight is ", jane.weight)
27     fmt.Println("Her speciality is ", jane.speciality)
28     // 我们来修改他的skill技能字段
29     jane.Skills = []string{"anatomy"}
30     fmt.Println("Her skills are ", jane.Skills)
31     fmt.Println("She acquired two new ones ")
32     jane.Skills = append(jane.Skills, "physics", "golang")
33     fmt.Println("Her skills now are ", jane.Skills)
34     // 修改匿名内置类型字段
35     jane.int = 3
36     fmt.Println("Her preferred number is", jane.int)
37 }

结果：

Her name is Jane

 Her age is 35

 Her weight is 100 

Her speciality is Biology

 Her skills are [anatomy] 

She acquired two new ones

 Her skills now are [anatomy physics golang] 

Her preferred number is 3
