Why not? I guess he has found some C# code and wants to use the
partitioning algorithm in his C program.

I disagree that string manipulation is all that hard in C. There's good
support in the CRT, including the function sprintf() that can handle all
of the string formatting functionality used in the original code (though,
itoa() and strcat() would work just as well). And the recursive nature of
the algorithm is a complete red-herring; C can handle the recursion every
bit as well as C# can.
But regardless, the guy didn't ask "what function do I use for this?" or
"how should I approach this problem?" He asked for someone else to do the
work. And if it really is as hard to convert to C as you imply, then the
request for someone else to do his work for him is that much more
unreasonable.

i'm not trying get my work done by someone else. i tried for 2 days to

in within 'partation' function is a big problem... (im not very

So thats y i wrote the algorithm with a language that im comfortable

Frankly, given that your question is about how to write C code, you should
post in a newsgroup for C programming. Use pseudo-code instead of C# for
broadest understanding of the question.
I already described in my previous posts functions in the CRT that would
be useful for you. Most of the rest of the code is just like C# anyway.
It seems to me that you should have enough information at this point to
get it working, but if you don't, a newsgroup for C programming would be a
much more appropriate place to find your answers.
When you post there, be sure to ask specific questions about what you're
having trouble with, rather than just asking for people to write the code
for you.
Pete
I wouln't think that this would be the place to ask that question.

For the same reason that, even though some people reading a C/C++

I am not so sure of that. I assume he found a piece of C# code that
seems to do what he wants and likes to have it translated to C.
ISTM there are two possible kinds of forums he can ask: A C# forum,
where people will know the source language and some will know the
target, and a C forum, where people will know the target language and
some will be able to read the source. IMO, both are appropriate groups
to ask a question concerning both languages.
Of course, if there were a "convert C# to C" forum, that one would be
the most appropriate.

As far as your other rationale...
ISTM there are two possible kinds of forums he can ask: A C# forum,
where people will know the source language and some will know the
target, and a C forum, where people will know the target language and
some will be able to read the source. IMO, both are appropriate groups

Well, I respectfully disagree. If the question is about _writing_ some
specific code, then the appropriate newsgroup is the one relevant to the
target language. If the question is about _reading_ some specific code,
then the appropriate newsgroup is the one relevant to the source language.
If a person has so little experience that they need help both with
_reading_ some specific dode and _writing_ that code in some other
language, then it's likely they really ought to be starting somewhere
else. Like learning at least one or the other of the languages. This
doesn't appear to be the issue here anyway (the OP states he's comfortable
with C#), but even if it were, it's not an argument for putting questions
pertaining to writing C code in a C# newsgroup.

I still don't quite see the problem. Even if you think it is not the
right forum, then simply ignore it. Fact is that the question is
about converting from C# to C. I still see no real harm in asking
in groups for both languages.
Frankly, it's more for the OP's benefit than anyone else's.
I mean, there's value in keeping a newsgroup on-topic.
Sure, I fully agree. But one can overdo it, too, IMO. This one may be
dubious, but it has some relation to C#, after all.

Only because the OP stated the algorithm in C#. He could just as easily
have used pseudo-code or some other descriptive technique.
There's _nothing_ about the original question that inherently relates to
C#. Any connection is artificial and arbitrary. More importantly, it's
one thing for the original post to have been made, but given that it was
it still makes sense to encourage the OP to seek a more relevant forum.
