CString or string.h ?

Hi friends I want to know yr ideas about string manipulation in VC++. I always like to use CString functions for string manipulation. I feel that it help me for fast coding and unwanted memory crashing. But my Team Leader says to use low lever string operation like using pointer, finding chars in a String, Searching chars. strcmp() and so on. He says it is fast execution. I feel what we want to do with string manipulations are already done in CString by low level ‘c’ coding .What is yr opinion . Is it right or wrong ?

If you want to stay close to the Windows API (converiting ANSI to BSTR), then CString is a good option. Also, the sprintf-like Format() function saves you a lot of headaches, shince it takes care of buffer overflow. On the other hand, if you care about portability (you don't own CString, and it might go the way VB6 went), std::string is the obvious choice. Both allow you access to constant pointers (CString::operator LPCTSTR(), std::string::c_str() ), which you can use as you would a plain old char *. If you think performance might be an issue, DON'T ASSUME, TEST. I did find quite a difference between CString and std::string when using STL containers - but that depends on implementation. In any case, never, never roll your own implementation. There are quite a few ready-made ones to choose from. I use (mostly) CString at the user interface layer, and std::basic_string at the business logic layer. Pablo_A

where someone says "hey! that was why it was so slow! CString comparisons are making it so slow..." If you're having performance problems with string comparisons, I'd suggest to change your algorithm so you reduce your string comparisons or even remove it. Binary search, quick sort, hash tables are some algorithms that come to my mind when we're talking about in-memory processing. If you're doing database manipulation or simple file parsing, a simple DFA would be unbeatable, as you'd exchange a lot of strcmp by a single array lookup for each character. If you're parsing complex languages, I'd suggest you to write a grammar in a parser construction toolkit, like ANTLR for C++. Probably, it'll beat anything your team leader will hand code. I don't see dead pixels anymore... Yes, even I am blogging now!

I think you allready know the answer. Yes, your boss is clueless and you are going to spend most of your time manipulating char tables instead of doing actual work. :( life is hard.

Your Team Leader is wrong. Overusing low level string manipulation is a good way to ensure that you have lots of very subtle, hard to find bugs - potentially including buffer overruns.
CStringitself is pretty quick anyway if you use it correctly, and code using it orstd::stringcan be a lot more maintainable. If he wants to spend time improving things, he should be reading something like Effective C++[^] rather than banging on about CStrings!

You should somehow get your TL to read this thread... (Thinking what might happen after that!!) :->

You should tell him that he's a lamer for using strcmp() and pointers, when there's inline assembler! (That ought to make him see the silliness in his own remarks)
