it's like java, but with struct awesomeness

e.g

void strcpy( char * src, char * dst ) {

  while ( *(dst++)=*(src++) );  // Try making that a one-liner in Java (without using library functions)!11

}

2/4/2009 10:05:34 PM

hardcore c++ is MUCH easier to read than hardcore perl



so thank your stars its just C++

2/4/2009 10:09:57 PM

^^ that's not C++

2/4/2009 10:15:35 PM

that is perfectly valid C++, though technically it's also C

do you want me to inline the whole fucking string class smarty pants

2/4/2009 10:16:37 PM

its also horrendously unsafe and insecure

copy a non terminated string and you just reformatted your harddrive.

try doing that in Java

2/4/2009 10:18:12 PM

its called memory segmentation you pedantic buffoon

get out of here

C++ for You++

The name of my AP Comp Sci text book.

2/4/2009 11:06:14 PM

and there's a reason you're a User Experience Designer and nowhere near a Unix system, kiljadn

the standard libc string functions operate on null-terminated strings because with memory segmentation (hardware accelerated range checking, if you will), the reality that with overwhelming probability any unterminated string will be terminated by some other null byte, and the fact that disks are not even memory mapped, it's not necessary to have a range value to insure safe operation nor is there any risk of formatting a disk

scud is so far from anything resembling reality it's comical

Earlier Java implementations owe their sluggishness in part to the excessive range-checking. Fortunately (and the reason I no longer despise Java) run-time optimization and the unrolling of function calls in later implementations has given with the other hand.

And I bet there is someone out there who would use a function like that and find a way to format a drive.

when I was at state they didn't really teach us how to use it... maybe how to run it until your program segfaults and find the line number/stack trace, but nothing really useful.

step 1 get that stick out of your ass because I was just fucking playin' and you made it serious
step 2 get ready for pwnage because here are the facts:

*First of all the phrase "reformat your harddrive" is a very famous and commonly used maxim to refer to behavior undefined by the C++ specification that conveys both a levity and a gravity to what exactly undefined means. Clearly it doesn't indicate that undefined behavior will reformat your drive...merely the the behavior is undefined and the universe of possibilities is wide open.
It's mentioned several times by Meyers in Effective C++ and can also be found in Sutter's Exceptional C++ which are both must reads if you ever intend to practice C++ in industry.
Believe it or not I've seen white papers that go out of their way to prove that it IS possible.

* As any decent C++ programmer should know - dereferencing an uninitialized, null, or otherwise invalid pointer produces undefined behavior
http://everything2.com/e2node/undefined%2520behavior
* The standard libc functions aren't C++, they are C - that being said the non 'n' functions have been effectively deprecated for nearly a decade9 because they are so notoriously unsafe.

* Oh yeah and to top it off, your shitty strcpy will completely choke on UTF-16/Latin-1 which happens to be the native encoding on modern Windows systems.

oh nice, the ol' "pull out a random pic from someone's own photo gallery trick," that's never been done before.

but the fact that you would do it in response to a post that's not even an attack on anyone, much less directed at you, means you must really think i'm special. i'm flattered. and only a minute after my post... were you just waiting for me to post something so you could finally make your retort from another thread?

either way, if that pic makes me gay, i guess i'm as comfortable with my gayness as you are with yours, so good day, sir.

C++ is a superset of C. Aside from externs and globals, there is no substantial difference. All C is valid C++, get over it.

char *strcpy(char *dest, const char *src); -- your own Wiki link

char is typedefed to the native character type of the platform. It won't choke, unless you specifically pass a wchar_t* into a function with a char* signature like a dumbass. If it offends you so much you can template it or overload it.

I've TA'd a C++ class and been writing C/C++ for over 10 years without ever encountering the "reformat your harddrive" jargon, and relied more on experimentation than texts to learn the language, but I'll permit that it's an amusing exaggeration of the possibilities on platforms that do not implement proper memory segmentation.

I'm not reading the rest of the links because you just seem generally butthurt at this point.
