map的value赋值

package main

import "fmt"

type Student struct {
    Name string
}

var list map[string] Student

//map的Value赋值
func main()  {

    list = make(map[string] Student)

    student := Student{"action"}

    list["student"] = student
    //list["student"].Name = "xd" //错误 cannot assign to struct field list["student"].Name in map

    tempStudent := list["student"]
    tempStudent.Name = "xd"
    list["student"] = tempStudent

    fmt.Println(list["student"])

}

map的遍历赋值

package main

import "fmt"

type People struct {
    Name string
    Age int
}

//map的遍历赋值
func main()  {
    //定义map
    list := make(map[string] *People)

    //定义student数组
    peoples := []People{
        {Name: "zhou", Age: 24},
        {Name: "li", Age: 23},
        {Name: "xing", Age: 22},
    }

    //遍历结构体数组，依次赋值给map
    for i:=0;i<len(peoples);i++{
        list[peoples[i].Name] = &peoples[i]
    }

    //打印map
    for k,v := range list{
        fmt.Println(k,"=>",v.Name)
    }

}
