Hello Jamal,
If they're using the win32 api I see no reazons to rewrite parts of
the C runtime library, since they can just link to the Microsoft one
as a dll, and this is guaranteed to be present in almost every windows
instalation, thus making necessary only the distribution of the
executable.
What I like about C and c++ is that ... yes, most part of languages
now adays are more apropriate to use in most part of situations, if we
take in acount the sppeed and the easier interface they offer ... but
when a really special requirement comes, when a really complex need
arises, when something pretty hard, fast and stable needs to be done,
then C and c++ are there, ready to be used and provide a way to solve
the problem. I don't think C is used to most part of things now adays,
but when no other language can provide a solution for a big problem C
is still there.
This creates a strange situation, in the sense that a C developper
won't meet a very big market for emploiment, if we compare it with,
let's say, the java one, but a C developer will ikely be necessary in
a complex or very low level senarius, and then the C developper will
need to really know what he /r she is doing, because whatever it is it
won't work if the developer isn't good enough. I think that, if you're
to work with C, there's no a mid place to stay ... or you're very good
on it or you won't succeed in finding a job or having satisfactory
results in your programs ...

When you say "I wrote a program that crashed Windows," people just
stare at you blankly and say "Hey, I got those with the system, for
free."
