Interesting Problem About Incrementing ++
Here is my code:

Code:
int startingPort = 200;
string tempPort;
stringstream out;
out<<startingPort;
tempPort = out.str();    //tempPort carries startingPort in string format

//convert tempPort to *char - currentPort going to be passed into getaddrinfo()
char currentPort[10];
strcpy(currentPort, tempPort.c_str());

while(startingPort <= 400)
{
                          //shows the first old value, does not show the incremented value
                          cout<<"******currentPort "<<currentPort<<endl;
       //move to the next port in the specified range
		startingPort++;

		//convert the incremented port to a string
		string tempPort;
		stringstream out;
		out<<startingPort;
		tempPort = out.str();
		char currentPort[10];
		strcpy(currentPort, tempPort.c_str());
                     
                          //works fine - incremented
		cout<<"TEST* currentPort "<<currentPort<<endl;
}

My program compiles, the problem is currentPort reset itself to 200 everytime a new loop starts...

This code is just example. Do you know why in every loop, the value reset itself?

locale::codes::langvar

Locale::Codes::LangVar(3)				User Contributed Perl Documentation				 Locale::Codes::LangVar(3)

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('arevela','alpha');
	  $lvar = code2langvar('arevela',LOCALE_LANGVAR_ALPHA);

       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.
