    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    The manual. Seriously. If you're in some flavour of unix, type:
    Code:
    man function-name
    If you're under windows, google "unix man function-name".
    long time; /* know C? */
    Unprecedented performance: Nothing ever ran this slow before.
    Any sufficiently advanced bug is indistinguishable from a feature.
    Real Programmers confuse Halloween and Christmas, because dec 25 == oct 31.
    The best way to accelerate an IBM is at 9.8 m/s/s.
    recursion (re - cur' - zhun) n. 1. (see recursion)

    Dear Cactus

    I'm using windows, i never tried to use Unix, I actually don't know how to begin working with Unix, I bought a book about OpenBSD and when I asked my college on school about this one, he said I should begin with Linux befor trying to enter the world of Unix .. I really didn't understand what he meant cauz I thought Linux is just one of the variants of Unix ..
    But anyway I am surviving with windows and at school if you choos networking as formation option then you will learn a second OS and that's Linux but I'm doing programming at software application level (High level) with Java and VB.net and now I want to learn programming at the software system level (low level) and that's why I choosed C and I think there is no better than C.

    Thanks

    if you are working with windows msdn.microsoft.com will be you friend aventually (maybe even hated friend )
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    OpenGroup.org, basically the on-line version of the man pages. Best way to find specifications for a standard function is to type "site:opengroup.org function_name" into google.

    Most of the standard C functions (C99) -> http://www.cplusplus.com/reference/clibrary/

    I usually just google "[c function] function", where [] is optional. (Though if you leave out "c function" you often get PHP hits first, so you just have to scroll a bit.) Either that or I google "man page" and use one of the hits to do a search.

    I like this online man page site for its in-depth explanations, though it doesn't have a search feature, so I usually just use google and click on its hit. (It's easy to spot with "opengroup" and all of those numbers.) I also like man.he.net because it has a search feature and the address is not that hard to remember.
