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++.

n1124, chapter 4, "Conformanc e": "The implementation shall not successfully
translate a preprocessing translation unit containing a #error preprocessing
directive unless it is part of a group skipped by conditional inclusion."

The diagnostic is covered in 6.10.5: "A preprocessing directive of the form
# error <pp-tokens_opt<new-linecauses the implementation to produce a
diagnostic message that includes the specified sequence of preprocessing
tokens."

Technically an implementation is indeed not required to "terminate
translation", but that was not what was claimed; just that it was
"prohibit[ed] [...] from translating", which it is. An implementation could
continue translating and delete the output only at the end, for example.

In n1124.pdf, it's [4#4]:

# The implementation shall not successfully translate a preprocessing
# translation unit containing a #error preprocessing directive unless it

I believe there's no similar clause in C89, though.

That's not what they have said; what they said was that they would
implement C99 features as customer demand warranted.
From:
http://groups.google.ca/group/comp.l...ed0a6d66938197

I asked if MS has any plans to support C99 in the next VisualC. This
is their answer. I think we should whine more :-)

We feel that C++ addresses this space sufficiently. In general we have
no plans to add any C99 features that duplicate functionality in C++
or conflict with it.

That also matches the feedback we have gotten from customers. In fact
the non interest in C99 is the clearest feedback I have seen of any
issue. The ratio of customers who don't want us to prioritize C99
features versus those who do is definitely higher than 100:1.

From:
http://msdn.microsoft.com/chats/tran...io_022703.aspx

Q: There is one single C99 feature that has grasped my desire:
"varargs" macros. They rock! Will you be implementing these at some
point?
A: I happen to think there'll pretty cool as well. We haven't had a
lot of demand for varargs macros. We happen to have an extension
'__noop' which can be used for some of the same purposes varargs
macros are (debuging printf's).

Q: Follow-up on the C99 "varargs" question, what, if anything, from
C99 will we see in the future from VC
A: In general, we have seen little demand for many C99 features. Some
features have more demand than others, and we will consider them in
future releases provided they are compatible with C++. It is more
likely we'll entertain C99 features if they are picked up in the next
version of the C++ standard.

Q: keyword restrict?
A: We are definitely considering restrict.
