How would i call a function that returns array to the variable which will suppose its of type array, so i can itterate it.

type User struct {
    char  string
    numb string
}
type Users []User

func main() {
    a := get()
    for i := range a {
        fmt.Println(i)
    }
}

func get() []User {
    return Users{"a","1","b","2","c","3"}
}
