C++ String Class Type

Pho · 2001-04-28T13:05:48

Hello all! Up until now, I used to tend the standard C-style character strings in all my OpenGL projects. You know, something like: const char *string = “How are you today?”; int iWidth = 640; char text[255]; sprintf( text, “Window width: %d”, iWidth ); Just recently I learned about this really cool standard C++ string class type. Basically, you include the following header: #include "string" and then use it like this: std::string sWindowName( “NeHe OpenGL Framework”); My problem concerns the way to write formatted data to a string. For instance, when using the old C style strings, I would do something like this: int iWidth = 640; int iHeight = 480; char text[255]; sprintf( text, “Width is: %d, Height is: %d”, iWidth, iHeight ); MessageBox( hWnd, text, “Window Dimensions”, MB_OK ); So does anybody know how to use this kind of formatting ( mixing strings with numbers particularly ) with the C++ string class type ? I would be thankful for any possible tips. Pho Edited by - Pho on April 24, 2001 8:30:27 PM Edited by - Pho on April 24, 2001 8:31:13 PM

I would be glad if there is a fact i missed. I''ve never seen sth. about ostringstream and istringstream.
I only know about ostrstream and. Is the i/ostringstream class part of standard C++ or isn''t it?
Wich Compiler do you use?

Curios Ben

P.S.Will test it on MS VC++ as soon as I''m home again

Ben_, std::ostringstream and std::istringstream (std::stringstream), are indeed defined as part of the C++ standard. Providing your compiler complies with the language definition, as of 1998, it should support the "sstream" header file.

Thanks, I''ve found it.
I will have to rewrite some of my code now. This class is really helpful and I was angry that there wasn''t one like that out there!!

Greetings Ben
