1.//对map中的struct赋值
type person struct {
id int
name string
}
func main() {
persons := make(map[int]person)
persons[0] = person{1, "a"}
log.Println(persons[0])
v, ok := persons[0]
if ok {
v.id = 0
persons[0] = v
}
log.Println(persons)
persons1 := make(map[int]*person)
persons1[0] = &person{1, "a"}
log.Println(persons1[0], ",", persons1)
_, ok = persons1[0]
if ok {
var p *person
p = persons1[0]
p.id = 5
(*persons1[0]).id = 10
}
log.Println(persons1, persons1[0])
}
