对我来说是这样的，

Access Linked Lists allow only sequential access to elements. Thus the algorithmic complexities is order of O(n) Arrays allow random access to its elements and thus the complexity is order of O(1) Storage Linked lists require an extra storage for references. This makes them impractical for lists of small data items such as characters or boolean values. Arrays do not need an extra storage to point to next data item. Each element can be accessed via indexes. Size The size of Linked lists are dynamic by nature. The size of array is restricted to declaration. Insertion/Deletion Elements can be inserted and deleted in linked lists indefinitely. Insertion/Deletion of values in arrays are very expensive. It requires memory reallocation.

除了在列表中间进行添加和删除之外，我更喜欢链表，因为它们可以动态地增长和收缩。

为什么是链表而不是数组?有些人已经说过，插入和删除的速度更快。

但也许我们不需要生活在两者的限制下，同时获得两者的优点……是吗?

对于数组删除，您可以使用'Deleted'字节来表示一行已被删除的事实，因此不再需要重新组织数组。为了减轻插入或快速更改数据的负担，可以使用链表。然后，在引用它们的时候，让你的逻辑先搜索一个，再搜索另一个。因此，将它们结合使用可以使您获得两者的最佳效果。

If you have a really large array, you could combine it with another, much smaller array or linked list where the smaller one hold thes 20, 50, 100 most recently used items. If the one needed is not in the shorter linked list or array, you go to the large array. If found there, you can then add it to the smaller linked list/array on the presumption that 'things most recently used are most likey to be re-used' ( and yes, possibly bumping the least recently used item from the list ). Which is true in many cases and solved a problem I had to tackle in an .ASP security permissions checking module, with ease, elegance, and impressive speed.

假设您有一个有序集，您还想通过添加和删除元素来修改它。此外，您需要能够以这样的方式保留对元素的引用，以便稍后可以获得前一个或下一个元素。例如，一本书中的待办事项列表或一组段落。

首先，我们应该注意到，如果您想在集合本身之外保留对对象的引用，那么您可能最终会将指针存储在数组中，而不是存储对象本身。否则你将无法插入到数组中-如果对象嵌入到数组中，它们将在插入期间移动，并且任何指向它们的指针都将无效。数组下标也是如此。

您的第一个问题，正如您自己所注意到的，是插入链表允许插入O(1)，但数组通常需要O(n)。这个问题可以部分克服——可以创建一种数据结构，提供类似数组的按顺序访问接口，其中读和写在最坏的情况下都是对数的。

Your second, and more severe problem is that given an element finding next element is O(n). If the set was not modified you could retain the index of the element as the reference instead of the pointer thus making find-next an O(1) operation, but as it is all you have is a pointer to the object itself and no way to determine its current index in the array other than by scanning the entire "array". This is an insurmountable problem for arrays - even if you can optimized insertions, there is nothing you can do to optimize find-next type operation.

我也认为链表比数组更好。 因为我们在链表中做遍历，而不是在数组中

链表比数组的维护开销更大，它还需要额外的内存存储，所有这些都是一致的。但是有一些事情是数组做不到的。在很多情况下，假设你想要一个长度为10^9的数组你无法得到它，因为必须有一个连续的内存位置。链表可能是这里的救世主。

假设你想用数据存储多个东西，那么它们可以很容易地扩展到链表中。

STL容器通常在后台有链表实现。
