STRCMP或字符串::比较？

问题描述

我要比较两个字符串。是否有可能与 STRCMP ？ （我想，它似乎不工作）。为字符串::比较的解决方案？

I want to compare two strings. Is it possible with strcmp? (I tried and it does not seem to work). Is string::compare a solution?

除此之外，有没有办法来比较字符串到字符？

Other than this, is there a way to compare a string to a char?

感谢争取早日意见。我是用C ++编码和是它为std :: string像有些人提及。
我没有贴code，因为我想学的一般知识，这是一个pretty长code，所以这是无关的问题。

Thanks for the early comments. I was coding in C++ and yes it was std::string like some of you mentioned.I didn't post the code because I wanted to learn the general knowledge and it is a pretty long code, so it was irrelevant for the question.

我觉得我学会了C ++和C中的差异，感谢指出了这一点。我会尝试，现在使用重载操作符。顺便说一句字符串::比较工作太。

I think I learned the difference between C++ and C, thanks for pointing that out. And I will try to use overloaded operators now. And by the way string::compare worked too.

推荐答案

有关C ++中，使用的std ::字符串，并使用字符串比较::比较。

For C++, use std::string and compare using string::compare.

对于C使用 STRCMP 。如果你（的我的意思你的程序的）字符串（由于某种奇怪的原因的）不是 NUL 终止，使用 STRNCMP 代替。

For C use strcmp. If your (i meant your programs) strings (for some weird reason) aren't nul terminated, use strncmp instead.

但是，为什么会有人的不的使用简单的东西如 == 为的std ::字符串
？

But why would someone not use something as simple as == for std::string?
