Hi everybody!
For a private project I'm doing at the moment, I need to learn pure C. I've been learning C++ for a while, but just leaving away the parts of the language, that I know belong to C++ just doesn't do the job all of the time. So, I'd like to know some good sources. I know, that searching for C tutorial on Google will give me lot's of results, but I have no idea, which of them are good and which aren't.
Also, I would like some reference on what is actually part of the language and what is part of the standard libraries.
Oh, I should mention that I have a reasonable amount of experience in Java. I know, C isn't OOP, but in many parts the syntax is very similar.
Greetings,
Nepomuk

Thank you. That would be this one, right? (Or for those, who can read german: this one.)

Yup, the English version is the one I was targeting; I don't know about the German
version but that could be the translation of the English version. K&R didn't write
many different books on C, so despite those dwarfs on the cover ... ;-)

I would like to know where you can't use C++.
The only place I have ever heard there is an issue is in the Windows drivers environment where you are dealing with paged code - and even there C++ has crept in.
C++ is designed to replace C.

At the moment, I'm writing a sort of kernel and, as you can see with the Linux kernel, many people prefer C over C++ for this sort of task. Now, I don't know either language well, but I'd like to be able to compare myself. So far, I haven't needed any objects and I can't use the standard libraries (including things like printf/cout and, annoyingly, malloc) anyway.
I might well use C++ in the end, but I'd like to learn C in any case. The minimum will be, that I get a better understanding of C++. Oh, and I might have to write a sort of Windows driver at some point (that has to do with a far away goal of the project).

If you can use the system calls sbrk() or brk() that manipulate the
size of your process' memory you can build your own malloc; K&R2 contains
a simple implementation of that function (and the free() function as well).

Jos

HELLO,
JosAH previously had advised me to read this book and now I own that one.
And yes, as JosAH said, K&R2 is certainly the bible of C. It is really a good (I'd better say "best" here) book for C. I'm presently reading to it.
THANKS......... ....

Everywhere where C++ is not available. We (my friends and I) developed a piece
of dedicated hardware, based on a small Atmel processor. There is no C++ compiler
available for that thingie; there is a fine C compiler available though. That's why.

I would echo this reply and add that there are many 100s of platforms for which there is a C compiler and no C++ compiler and that there are a far number of platforms that although they have a C++ compiler the implementation is so buggy that you wouldn't want to use it.
