Where can I find a list of C keywords (and / or C ++) covering K & R1 / 2, C89-C1X and their origin?

Question

I was acquainted with numerous coding instructions, each of which gave recommendations on the name of "things". One specific C89 naming rule raised this question: it was explicitly forbidden to use the name "new" for a variable, because in C ++ it is a keyword.

It made me think about the following standards, the C99 is well documented, but the C11 is relatively new (2014). And the Standards Committee has several extensions that are still in the works.

Therefore, I am wondering if anyone can provide a list with keywords and their origin in order to create a set of naming rules, including reasons why several names should be avoided.

Although, strictly speaking, complex not a keyword, similar definitions are best included. And C ++ information is also welcome.

Answer 1

Thanks for all the answers and comments, but just having a list of keywords was not quite my intention. Special,

... and their origin ...

apparently missed. But when compiling a coding guide, you always need to provide justification for each limitation.

That's why I started collecting my own data and putting it in a document. I'm still working on this, especially the AM1 amendment to the C90 standard in 1995 was not fully included, for C ++ only the latest C ++ 11 standard was used (partially), several technical reports still need to be included, etc. But since I am not currently pursuing a lot of updates due to the workload, I put a draft version to download on my site.

If you're interested, look here: Reserved words in C (pdf) . Additions and corrections are always welcome, contact information on my site.

FWIW.

C11 has new keywords. Some of them are Alinhas, Alinjof. A complete list can be found at http://www.sdlczone.com/complete-list-of-c-keywords/
