[golang]map的value赋值和遍历赋值

1、=========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"])





}

2、=========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)

	}



}
