Apparently using incremental ops multiple times in the same statement is undefined in C.
Yes, the behavior in those cases is unspecified (except that i should be 7 at the end). But with compilers I've used in the past, the results I quoted was what you would usually get. I had seen compilers that would give one of:
before (both with or without increments in all cases), but I had never seen one that did:
with immediate increments on i++ and using both values (3 * 4) on one, but doing both ++i operations and using the final value (7 * 7) on the other. Oh, well.
I'm an intern at a company that recently bought out another business. In doing so, they inherited a unix system that contains files which they need to retrieve. No one in the company, including myself, really understands or knows unix so please respond with the true assumption that I'm a unix... (1 Reply)

Hello all,
I am trying to delete all the lines in a particular file having a pattern. The problem is that it has special characters and for some reason is not doing the job.
For eg.

Good day, everyone!
Could anybody explain me the following situation.
If I'm running similar script:
Var="anna.kurnikova"
Var2="Anna Kurn"
echo $Var | tr -t "$Var" "$Var2"
Why the output is :
anna KurniKova
instead of Anna Kurnikova?
:confused:
Thank you in advance for any... (2 Replies)
I come across an entry in cron which is in such:
0 * * * *
What is the first 0 indicating? 0 minute? meaning a script cron as such will run every minute? :confused: (2 Replies)
See code below. It appears that i and j inhabit the same address yet hold different values. Can anyone shed light on this?
int main() {
const int i= 3;
int* j = const_cast<int*>(&i);
*j = 5;
cout << j << endl << &i << endl;
cout << *j << endl << i;

Hi folks,
If a declare a direct hash , then the hash element works fine.
my %test = ("test",1);

locale::codes::langext
Locale::Codes::LangExt(3pm) Perl Programmers Reference Guide Locale::Codes::LangExt(3pm)NAME
Locale::Codes::LangExt - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangExt;
$lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic'
$code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langext_codes();
@names = all_langext_names();
DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, 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 extensions. 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:
$lext = code2langext('acm','alpha');
$lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.
This is the default code set.
ROUTINES
code2langext ( CODE [,CODESET] )
langext2code ( NAME [,CODESET] )
langext_code2code ( CODE ,CODESET ,CODESET2 )
all_langext_codes ( [CODESET] )
all_langext_names ( [CODESET] )
Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] )
Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME )
Locale::Codes::LangExt::delete_langext_alias ( NAME )
Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
