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

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 :)

数组和链表之间的区别在于，数组是基于索引的数据结构，每个元素都与一个索引相关联，而链表是使用引用的数据结构，每个节点都被引用到另一个节点。在数组大小是固定的，而在链表大小是不固定的。

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。

首先，在c++中，使用链表应该不会比使用数组更麻烦。对于链表，可以使用std::list或boost指针列表。链表与数组的关键问题是指针需要额外的空间和糟糕的随机访问。你应该使用链表，如果你

你不需要随机访问数据 您将添加/删除元素，特别是列表中间的元素

合并两个链表(特别是两个双链表)比合并两个数组快得多(假设合并是破坏性的)。前者取O(1)，后者取O(n)。

编辑:澄清一下，我在这里指的是无序意义上的“合并”，而不是归并排序。也许"串联"这个词更合适。
