字符串搜索算法使用string :: find（）c ++ [英] String search algorithm used by string::find() c++

问题描述

它如何比cstring函数快？是类似的源C？

how its faster than cstring functions? is the similar source available for C?

推荐答案

没有C ++标准库的标准实现，但你应该能够看看你的编译器附带的实现，看看它是如何工作的自己。

There's no standard implementation of the C++ Standard Library, but you should be able to take a look at the implementation shipped with your compiler and see how it works yourself.

一般来说，大多数STL函数不比它们的C对应的速度更快。它们通常更安全，更一般化，并设计为适应比狭义目的C等同物更广泛的情况。

In general, most STL functions are not faster than their C counterparts, though. They're usually safer, more generalized and designed to accommodate a much broader range of circumstances than the narrow-purpose C equivalents.
