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.

Linked lists have several advantages over arrays. Elements can be inserted into linked lists indefinitely, while an array will eventually either fill up or need to be resized, an expensive operation that may not even be possible if memory is fragmented. Similarly, an array from which many elements are removed may become wastefully empty or need to be made smaller. On the other hand, arrays allow random access, while linked lists allow only sequential access to elements. Singly-linked lists, in fact, can only be traversed in one direction. This makes linked lists unsuitable for applications where it's useful to look up an element by its index quickly, such as heapsort. Sequential access on arrays is also faster than on linked lists on many machines due to locality of reference and data caches. Linked lists receive almost no benefit from the cache. Another disadvantage of linked lists is the extra storage needed for references, which often makes them impractical for lists of small data items such as characters or boolean values. It can also be slow, and with a naïve allocator, wasteful, to allocate memory separately for each new element, a problem generally solved using memory pools.

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。

Eric Lippert最近发表了一篇关于数组应该保守使用的原因之一的文章。

While many of you have touched upon major adv./dis of linked list vs array, most of the comparisons are how one is better/ worse than the other.Eg. you can do random access in array but not possible in linked list and others. However, this is assuming link lists and array are going to be applied in a similar application. However a correct answer should be how link list would be preferred over array and vice-versa in a particular application deployment. Suppose you want to implement a dictionary application, what would you use ? Array : mmm it would allow easy retrieval through binary search and other search algo .. but lets think how link list can be better..Say you want to search "Blob" in dictionary. Would it make sense to have a link list of A->B->C->D---->Z and then each list element also pointing to an array or another list of all words starting with that letter ..

A -> B -> C -> ...Z
|    |    |
|    |    [Cat, Cave]
|    [Banana, Blob]
[Adam, Apple]

Now is the above approach better or a flat array of [Adam,Apple,Banana,Blob,Cat,Cave] ? Would it even be possible with array ? So a major advantage of link list is you can have an element not just pointing to the next element but also to some other link list/array/ heap/ or any other memory location. Array is a one flat contigous memory sliced into blocks size of the element it is going to store.. Link list on the other hand is a chunks of non-contigous memory units (can be any size and can store anything) and pointing to each other the way you want. Similarly lets say you are making a USB drive. Now would you like files to be saved as any array or as a link list ? I think you get the idea what I am pointing to :)

根据你的语言，可以考虑以下一些缺点和优点:

C编程语言:当使用链表(通常是通过结构指针)时，必须特别注意不要泄漏内存。正如前面提到的，链表很容易洗牌，因为我们所做的只是改变指针，但是我们会记得释放所有的东西吗?

Java: Java具有自动垃圾收集功能，因此内存泄漏不会成为问题，但是对于高级程序员来说，隐藏了链表的实现细节。从列表中间删除节点等方法的过程比该语言的一些用户所期望的要复杂得多。
