觉得比较搞 从左往右时得设得值大概是忽略之前得值进行 但搜索还是从最左开始 就是如果with在前4个字符得话 结果还是12
但是负值得话 搞不懂了 看了个例子 s1＝“Hello hello goodbye" s2＝”hello''    find(s1, s2, ''i'', -99) 的值是7
说是如果负值的长度大于string长度就从最右从左开始搜索 可是数起来不对 即使是从左往右的话 值应该是1
哪位高人指点下下？

13# yuyyy

因为99要比字符串的长度大，而且是负号，所以从最右端开始向左找。先找到的是第二个‘HELLO'，它是从位置7开始的。所以值是7

那就是find结果都是从左开始算起来的 无论从哪个方向

对，所指的position，都是从左边开始数起的。
你举了个非常好的例子，谢谢。终于搞明白了。

想一想，如果同一个东西的标志， 这里指的是所寻找的字符（串）的位置，都不固定的话，还怎么用？另外也未必要扣得这么细吧，find 的作用是什么？你未必想知道你要找的东西在哪个具体的位置上，而是要确定其中有没有。正反左右就由他去吧，不是吗？

一群热心人啊
