C++/STL 字符串：如何使用通配符模拟正则表达式之类的函数？
我想使用通配符比较 4 个字符串。
例如：
std::string wildcards[]=
{"H? ", "RH? ", "H[0-5] "};
/*in the last one I need to check if string is "H0 ",..., and "H5 " */
是否可以只用STL来实现？
谢谢， 阿曼.
编辑：
我们可以在没有 boost.regex 的情况下做到这一点吗？
或者我应该向我的项目添加另一个库依赖项？:)
I would like to compare 4 character string using wildcards.
For example:
std::string wildcards[]=
{"H? ", "RH? ", "H[0-5] "};
/*in the last one I need to check if string is "H0 ",..., and "H5 " */
Is it possible to manage to realize only by STL?
Thanks,
Arman.
EDIT:
Can we do it without boost.regex?
Or should I add yet another library dependences to my project?:)

使用 Boost.Regex
Use Boost.Regex
不 - 你需要 boost::regex
No - you need boost::regex
正则表达式就是为这类事情而设计的。我可以理解您不愿意避免依赖，但在这种情况下，这可能是合理的。
您可以检查您的 C++ 编译器，看看它是否包含任何内置正则表达式库。例如，Microsoft 包含 CAtlRegExp。
除此之外，您的问题看起来编写自定义代码并不难。
Regular expressions were made for this sort of thing. I can understand your reluctance to avoid a dependency, but in this case it's probably justified.
You might check your C++ compiler to see if it includes any built-in regular expression library. For example, Microsoft includes CAtlRegExp.
Barring that, your problem doesn't look too difficult to write custom code for.
您可以在不引入新的库依赖项的情况下完成此操作，但这样做最终您需要自己编写正则表达式引擎（或至少是正则表达式引擎的子集）。
您有什么原因不想为此使用库吗？
You can do it without introducing a new library dependency, but to do so you'd end up writing a regular expression engine yourself (or at least a subset of one).
Is there some reason you don't want to use a library for this?
