Hi,
I am working on a porting project to port C/C++ application from
unixware C++, AT&T Standard components to g++ with STL on Linux. This
application has been working properly on Unixware/C++/AT&T componets
environment.
I have been able to compile all modules after making necessary changes
in LINUX/gcc/STL environment. We have two templates defined XList and
XMap.

Hi!
I've been thinking about passing parameteras using references instead
of pointers in order to emphasize that the parameter must be an
object.
Exemple:

Hi,
In one of my interview I was asked a question, whether using pointers for
argument is efficient then reference or not.
i.e. void fun(Complex *p)
void fun(Complex &ref)
can somebody tell me which one will be more efficient and why?
as far as i know both must be same, because i read somewhere that internally

Is there any harm in passing an object into a method with the 'ref'
keyword if the object is already a reference variable? If not, is
there any benefit?

Hello all,
I'm passing a reference to a class into the constructor of a form, like
so: public MyForm(int count, ref Area myArea) {...}
How can I use myArea outside the constructor? Should I create another
Area and assign myArea to it (ie: Area foo = myArea;) or is there a
better way?

I'm reading the MS press C# book and there seems to be a contradiction.
Please tell me which one is correct, 1 or 2.
Thanks!
Jeff
1. First it gives the code below saying that it prints 0 then 42.
They say that 42 is printed the second time since the value was wrapped in a
class and therefore became passed by reference.
(sorry for any typos I am a newbie here ;-)

I have added a reference of this component.
During form_load, I have specified the grammar. (list of words that are to
be recognised).

But now I need to enter data into textbox through speech. (i e) perform
dictation.
But the speech engine doesn't recognise words that are not specified...

Can we confirm the following? also someone said, Java also has
"reference" like in C++, which is an "implicit pointer":
Pointer and Reference
---------------------
I am starting to see what pointer and reference are and how they
relate
to each other.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
