Saying code like that "depend[s] on undefined behavior" is too kind. Anyone who writes code that assumes the location of a variable based on the location of another variable is bat-!*()% crazystupid.
FWIW, multiple definitions on one line are a bad idea for other reasons, too.
What's this mean:
declares an object of type pointer to char named ptrA and an object of type char named ptrB. It also means that I will never hire the programmer that wrote this. Either they don't understand the rules of C or C++, or they don't understand that you shouldn't name a variable ptrx unless that variable is declared to be a pointer type (unless they're entering some kind of code obfuscation contest).
There is nothing wrong with declaring multiple objects with a single declaration (whether or not it is on one line or spread across several lines).
When writing code, use a set of style guidelines and be consistent. And if the guidelines you use aren't "common practice", make sure that anyone who will ever need to maintain your code also has a pointer to a written set of the guidelines used.
Is it possible, and if so, how can I assign a static IP address to my RedHat 8.0 machine. I am using a Linksys router/switch with DHCP enabled. I have a small linux/windows2000 LAN at home.

Hi
I want to know when and where memory for static variables are allocated in a C program. If it allocates during compilation will memory be allocated for the variable "i" during compilation itself.

int main(){
printf("%d", count());
return 0;
}

Hi all,
Sorry I make a mistake,the title should be "How to statistic the average value "
I do five times about "mv 123 to 456"
and do five times about "mv 456 to 123"
As we know,"time" can get the real usr sys value,

And I want to generate my library(libzzz.a), libzzz.a will use libxxx.a and libyyy.a
I wan't my application only use libzzz.a, (means libzzz.a had include libxxx.a, libyyy.a), how can I do that? Thank you.

locale::codes::langvar
Locale::Codes::LangVar(3pm) Perl Programmers Reference Guide Locale::Codes::LangVar(3pm)NAME
Locale::Codes::LangVar - standard codes for language variation identification
SYNOPSIS
use Locale::Codes::LangVar;
$lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic'
$code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langvar_codes();
@names = all_langvar_names();
DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
the IANA language registry.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
registry codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language variations. A code set may be specified using either a name, or
a constant that is automatically exported by this module.
For example, the two are equivalent:
$lvar = code2langvar('en','alpha-2');
$lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);
The codesets currently supported are:
alpha
This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.
This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".
This is the default code set.
ROUTINES
code2langvar ( CODE [,CODESET] )
langvar2code ( NAME [,CODESET] )
langvar_code2code ( CODE ,CODESET ,CODESET2 )
all_langvar_codes ( [CODESET] )
all_langvar_names ( [CODESET] )
Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )
Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )
Locale::Codes::LangVar::delete_langvar_alias ( NAME )
Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
