Hello Grp,
Correct me if I am wrong.
static member functions can act only on static member varaibles.It can
accessed by using the name of the class.
Then why is there an access controller.
what does a private static member function mean?
Thaanx in advance for any advice
Rgds,

Are static friend functions allowed? I tried this
today with gcc-3.2 without success. The function
was not a class member. The friend statement was
interpreted as meaning "extern", and this was
reported incompatible with a previous static
declaration.
Chapter and verse would also be helpful. I looked
around but didn't find anything.

Question: How do friend functions and static member functions differ in
terms of functionality? I mean, neither necessarily needs an object of
the class to be created before they are called and either has access
only to static members of the class (ie. assuming no object of the
class is in scope - neither by arguments recieved nor by local
declarations). Any static member function like this:
//accessing static member i
static void...

I want static functions of classes Uam and Bar to be friends of class
Foo.
There is no problem with Uam::uam().
But class Bar has a member of Foo type: member Bar::m_foo, so one can't
put Bar definition before Foo definition.
As a result, a compiler rejects
friend void Bar::bar(); // in class Foo

Hi all,
I've got a question about writing a library. Let me characterize that
library by the following:
* there is a class A which is available to the user
* there is a class B that is used in severel 'underwater operations'
* there is a list which stores objects of class B
There are several issues I'm not sure about:

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
