CString函数 | CString

本文介绍了CString函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述我想对字符串执行以下操作： 1）检查前四个字符是否为DATA 2）从以下字符串DATA 123 xyz中获取中间的单词。（中间词是可变长度） - 提取123。 3）从以下字符串中获取最后一个单词/数字数据发送1467436267 我应该使用哪些功能来实现这一目标？我是C ++的新手，并且发现字符串操作很棘手。 I want to do the following to strings: 1) Check if first four characters are "DATA" 2) Get the middle ''word'' from the following string "DATA 123 xyz" (themiddle word is variable length) - extract the "123". 3) Get the last word/number from the following string "DATA SEND 1467436267" What functions should I use to achieve this? I''m new to C++ and findingstring manipulation tricky.推荐答案如果你使用CString，它为此提供了很多设施。看看 at - CString :: Left CString :: Mid CString ::正确 CString ::查找 CString :: Tokenize 问候， Hugh If you use CString it provides lots of facilities for this. Have a lookat - CString::LeftCString::MidCString::RightCString::FindCString::Tokenize Regards, Hugh CString不是标准的C ++类。查看microsoft.public。* newsgrouop for CString。对于std :: string，请使用： std :: string :: substr（）， std :: string :: find_first_of（） std :: string :: find_last_of（） CString is not a standard C++ class. Look in a microsoft.public.*newsgrouop for CString. For std::string, use : std::string::substr(),std::string::find_first_of()std::string::find_last_of() ....这是发布到microsoft.public.vc.language和 microsoft.public.vc.mfc我可能会补充说，我们最近想出了CString规则的结论！ :) - - Mark Randall http://zetech.swehli.com 那些认为他们知道一切的人对那些人来说是一个很大的烦恼> 我们的人 Isaac Asimov .... This is posted to microsoft.public.vc.language andmicrosoft.public.vc.mfc where, I might add, we recently came up with theconclusion that CString rules! :) --- Mark Randall http://zetech.swehli.com "Those people that think they know everything are a great annoyance to thoseof us who do"Isaac Asimov 这篇关于CString函数的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
