strcmp或string :: compare？ [英] strcmp or string::compare?

问题描述

我想比较两个字符串。是否可以使用 strcmp ？ （我试过，它似乎不工作）。 string :: compare 一个解决方案？

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?

$ c> string 至 char ？

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

感谢早期的评论。我在C ++编码，是的 std :: string 像你提到的一些。
我没有发布代码，因为我想学习一般知识，它是一个很长的代码，所以这是不相干的问题。

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.

我想我学到了C ++和C之间的区别，感谢你指出。现在我将尝试使用重载运算符。 string :: compare 也可以。

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

C ++，使用 std :: string 并使用 string :: compare 进行比较。

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

对于C，使用 strcmp 。如果您的（我的意思是您的程序）字符串（由于某些奇怪的原因）不是 nul code> strncmp 。

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

但为什么有人不是 $ c> == std :: string
？

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