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.

It's easier to store data of different sizes in a linked list. An array assumes every element is exactly the same size. As you mentioned, it's easier for a linked list to grow organically. An array's size needs to be known ahead of time, or re-created when it needs to grow. Shuffling a linked list is just a matter of changing what points to what. Shuffling an array is more complicated and/or takes more memory. As long as your iterations all happen in a "foreach" context, you don't lose any performance in iteration.

使用链表的唯一原因是插入元素很容易(删除也很容易)。

缺点可能是指针占用大量空间。

关于编码就更难了: 通常你不需要代码链表(或只需要一次)他们包括在内 STL 如果你还是要做的话，它就不那么复杂了。

这里有一个快速的方法:移除物品更快。

由于数组本质上是静态的，因此所有的操作 比如内存分配发生在编译的时候 只有。因此处理器必须在运行时投入更少的精力。

除了插入和删除方便之外，链表的内存表示方式也不同于数组。对于链表中的元素数量没有限制，而在数组中，您必须指定元素的总数。 看看这篇文章。
