why still use C?

no this is no trollposting and please don't get it wrong but iam very
curious why people still use C instead of other languages especially C++.

i heard people say C++ is slower than C but i can't believe that. in pieces
of the application where speed really matters you can still use "normal"
functions or even static methods which is basically the same.

in C there arent the simplest things present like constants, each struct and
enum have to be prefixed with "struct" and "enum". iam sure there is much
more.

i don't get it why people program in C and faking OOP features(functi on
pointers in structs..) instead of using C++. are they simply masochists or
is there a logical reason?

i feel C has to benefit against C++.

This is what C++ defines encapsulation as, sure. But encapsulation was
around before C++ you know.Try to define it without using C++isms,
before you spout caeculum tauri.


Without language support for encapsulation, attempts to reference
something from inappropriate locations in the code is something that
can only be prevented by very careful checking by fallible human
beings during code reviews. With such language support, some such
errors can be automatically checked for by the compiler.


I've no intention of arguing contrariwise. I'm merely pointing out
that "class", "friend class" "derived class" etc are C++ isms which do
not /define/ encapsulation, but /implement/ it. There are other ways
to do the same thing.

No its an int. For goodness sake, stop now, you're showing woeful

> The type of 'a' is int. The C99 standard, section 6.4.4.4 paragraph 2,
says:

An integer character constant is a sequence of one or more
multibyte characters enclosed in single-quotes, as in 'x'.

Was is the same in other versions of C besides C99?
(In C++, a character constant has type char, and sizeof('a') == 1.
We don't discuss C++ here.)


template <class T>
void FillBuf(T * buf, int nelements)
{
memset(buf, 0, sizeof(T)*nelem ents);
}

Would be very dangerous called with a char argument if C++ would behave like
C
in this context.

If you post in comp.std.c and don't understand the C language then you
deserve everything that is coming. And if you don't know why that is so

I don't think you did understand a thing. You should _really_ stop
posting to comp.std.c for a year or so; by that time people might have
forgotten what a fool you are making of yourself right now.

I don't think there was any call for that.


Au contraire, I think everybody has been showing remarkable constraint
so far. I would like to point out that again and again he was given the
advice to read up on stuff before blurting out, and *wham* there comes
another one.

I was tempted for just a second to go across cody's posts of the last
couple of days and collect some of the highlights, but that would be
uncalled for. I would hope though that some gentle and, perhaps,
not-so-gentle reminders of silly behavior would help to bring about a
change.

It is important to consider that he didn't ask a question, he was trying
to answer it. Obviously, he has been unable to get his MSVC compiler to
compile in C mode. This would be amusing in a rather sad way, were it
not for the fact that he stated:
sizeof (int)==sizeof ('a') is never true on no C nor C++ compiler on
this world.


There's matters of intellectual hygiene to consider. Extrapolating one
(1) observation to a statement of such generality (obviously unburdened
by knowledge) warrants a slight slap on the wrist.

The reason I take some issue with this is that it took me the better
part of two hours to reply to his original "Why still use C?" post,
under the assumption that he wanted an answer. Now it appears he's not a
troll in the traditional sense, but his attitude definitely needs some
work. He's acting like a kid sitting for the first time at the grown-ups
table, trying to take part in the conversation while he's supposed to
just sit in and listen.

Just my 5 eurocents,

Best regards,

Yes. If you had carefully read question 8.9 of the C FAQ, you
wouldn't have had to ask that; "ANSI Sec. 3.1.3.4" is a reference to
the previous version of the C standard.
(In C++, a character constant has type char, and sizeof('a') == 1.
We don't discuss C++ here.)

[C++ code snippet deleted]

We don't discuss C++ here. Really. If you'd like to discuss C++,
there are several C++ newsgroups. (There's also a C++ FAQ you should
read before you post there; google "C++ FAQ" to find it.)

If you think that it is clever or smart to bully new subscribers,

That's a far cry from your previous statement:
sizeof (int)==sizeof ('a') is never true on no C nor C++ compiler
on this world.


Ok, you made the honest mistake to not properly instruct your compiler
to behave as a C compiler (there's a flag for that). The not-very-clever
thing to do is to extrapolate this to the grandiose statement you made
earlier. You do realize this no doubt.

The funny thing is, you're probably a nice guy and all. Judging from
your posts you show some genuine interest in C/C++ issues, combined,
unfortunately, with a lack of in-depth of knowledge of these topics.

Now from your viewpoint, I will probably come across as an old pedantic
arrogant fart, but in reality it's not that bad, I can assure you - I'm
not _that_ old ;-). So putting aside all heated posts of the last days
for a moment, I would just urge you to take in the advice given on
several occasions (to think & learn a bit more before you type).

Nobody's perfect and mistakes are ok, but when you are pointed to
similar mistakes on several occasions, this is often a good clue that
you need to adjust a bit.

As to the flags, I think you'll need '/TC'. For good measure I'd suggest
you put in '/W4' as well, this will give a lot of warnings;
understanding them can really shape up your understanding of C.

Best regards,
