Standards

i saw lots of convos where programmers say that "this" fall under C98 standard and "that" fall under ANSI or whatever other standard is there...

my question is .. how do you guys learn what things go under wich standard (and) what things work with what standard??? do you read books about C\C++ standards or something???


any help would be appreciated..

Yeah, pretty much. If you don't have a copy of the standard itself (whatever year), then look for some books on the subject. One point of reference is "C: A Reference Manual, 5th Edition". It covers a touch of C++, but mainly goes over the various standards. Basicly just jump over to your favourite book seller and search for "C" "standard". Then read the reviews, look in the book if you can. I have a number of them, but the 5th Ed is what's handy.

Well you can get the last public draft of C99 for free from here
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n869/

If you want a proper standard, then visit
http://webstore.ansi.org/ansidocstor...FIEC+9899-1999

This contains some information on what happened between C89 and C99

thanks alot guys

It's a good idea to get a copy of the standard for whatever language you plan on talking about here, if only so that you can use it as ammunition.

its not neccessary , is it?? (learning about the old standards)

i think of it as gaining more knowledge of the past , like history maybe...

what do you think??

That depends entirely on what compiler you're using. I mean, if you're still stuck in the stone age ...

lol
do you think aaronc gets the point yet?

>its not neccessary , is it?? (learning about the old standards)
It couldn't hurt to learn where the differences and traps are. You may find yourself maintaining legacy code and knowledge of past standards (or lack thereof) can be mighty useful.

but their server is so slow that

Don't look a gift horse in the mouth.

it was downloading with 250 bytes/sec..

Patience, Grasshopper.

does that happens only to me?

Yes, everybody hates you. This is part of their way of showing it.

I'm don't think winzip can open .gz files.

IIRC, the pdf.gz isn't actually zipped at all, it's just a badly named pdf file.
Unless they've since fixed it.

It can, at least the later version I am sure of, the older ones, don't count on it.

It definately isn't a gzipped file. I tried last night with both of these commands

Code:

 tar -xzvf n869.pdf.gz 
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Error exit delayed from previous errors

and without the -z option; same errors. I renamed it to n869.pdf and did this

Code:

xpdf n869.pdf

and got these errors

Code:

Error: May not be a PDF file (continuing anyway)
Error (0): PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table

. So I assume something is wrong with the file. I have an idea; just go and get the txt file

linuxdude, you wouldn't use tar because it is not tar, only gzipped. To un-gunzip it you have to use the gunzip command:
gunzip n869.pdf.gz
