寻找指针的起源

Question

如果你有一个object1和一个指向object2的指针,我们当前在Object 2中,那么我们可以从object2到object1吗？怎么样？

 (OBJECT1) --------> (OBJECT2)
                      we are here and we don't know where/what OBJECT1 is

Answer 1

不,假设您有几个指向OBJECT2的指针

(POINTER1) ------------\
(POINTER2) -------------\
(POINTER3) --------------> (OBJECT2)
.....      -------------/
(POINTERN) ------------/

当你"上升"时,你应该去哪个指针？
