If Code Project can get organized, submit a petition and... 1. get "foreach" construct as part of ANSI standard for C++ 2. augment stdio with an XML parser :) Norman Fung

If those features are something you want to see in your programming language, why not use Java or C# instead of polluting C++?

I do. But I also program C/C++/Win32/MFC. And a great deal of existing inventories are still written in C/C++, not to mention that you can compile your ANSI C++ library and get it run on UNIX box. Norman Fung

Wouldn't work in C++ unless you're willing to see C++ mandate enumerable interfaces to arrays. I'm not willing to see such a mandate :) I don't find it that difficult to write a for loop or a do/while loop that takes into account the peculiarities of the container object I'm working with.

But do we need foreach?, I admit that I haven't given it a lot of thought, but there is bound to be a lot of issues involving the implementation. What kind of container should be the parameter?, and what would be the bloody point of it, if the runtime support for type checking (RTTI), as i recall is possible, is turned off?

template
   Function for_each(
      InputIterator _First, 
      InputIterator _Last, 
      Function _Func
   );

It's already part of the standard. If you really want a foreach rather than a for_each, add in:

#define foreach for_each

Well, how am I going to write that amazing program that does everything without being given the exact bits I need as part of the toolset? <WHINGE CLASS=VB_PROGRAMMER IDIOCY=MORE_MORONIC_THAN_USUAL> Why can't I write a media player that exports playlists as XML for my blog, generates JPG images on the fly for trippy visualisations and streams the audio to a thousand listeners in 10 lines of code and some controls on Form1? Then records all the statistics in SQL Server and processes them into a report for other people, transferred using EDI. In a second 10 lines of code and another control on Form1. And a third set of 10 lines of code can manipulate the Bluetooth dongle into a molecularising nano-constructer, and make me a real, live pony called Blossom Flower. </WHINGE> And this is why C++ shouldn't have a standardised, builtin, XML parser - because then the VBers would demand to be able to do the above :-)

Greedy, yes. ;P Would you recommend an Open Source C/XML parser though? Norman Fung

:laugh::laugh::laugh::laugh: You remind me of someone over on http:/www.dvdrhelp.com[^] about a year ago. At the time a couple of programs had been released that did amazing things in compressing a 2 layer DVD to a single layer without losing all that much quality. Anyway, this guy was somewhat dissatisfied with either offering and had this 'amazing' idea of how it could be much better. All he needed was a programmer to write a couple of 'easy' pieces to his grand scheme. I must confess I did play with his mind a bit :) Rob Manderson **Paul Watson wrote:**What sense would you most dislike loosing? Ian Darling replied.

If I could I would. Alas, I haven't dabbled in XMS yet (but it will happen) :) Rob Manderson **Paul Watson wrote:**What sense would you most dislike loosing? Ian Darling replied. Telepathy Then I'd no longer be able to find out everyones dirty little secrets The Lounge, December 4 2003

Thanks. Will look it up. In case if someone is curious: SAX[^] Norman Fung

How about Xerces[^], from the Apache group? OK, C++ rather than C.

std::for_each already exists in <algorithm> My article on a reference-counted smart pointer that supports polymorphic objects and raw pointers

Tim Smith

The STL for each is a primitive excuse for a for each. The construct is a kludge. Not to mention that even people like Meyers produce slower and more obscure bugs with this nasty construct trying to get it to do what they want. A true for each would be nice. Tim Smith I'm going to patent thought. I have yet to see any prior art.

Joe Woodbury

Boo! Hiss! If we're going to have a petition, why not get rid of the absurd abbreviations for wide string functions and, while at it, change wchar_t to wchar? By rule, unicode equivilants of standard library functions should simply have a 'w' in front of them.

haha.. but it's the underscore that make us proud C++ programmers. Norman Fung
