Forgive me if I'm wrong but I think there is something like an extra
member scope in classes.
for example:
class abc {
ostream & operator << (ostream &, const abc &);
istream & operator >> (istream &, abc &);
private:

I've heard that some compilers reserve the '_' starting a symbol for system
variables/symbols. I can not find this documented anywhere (so far). I've
used an '_' at the end of member variables (ie. Uint16 bar_; ) to
distinquish private fields, but this does not stand out as much as if the
'_' were at the begginning of the name as in the following class
declaration.
class Foo {
private:
Uint16 _baz;

Either I have found a puzzle, or I am just being stupid. Inside a
namespace I have a class with a static const double member. The
member is not an int so I cannot initialise it within the class, I
have to initialise it outside the class. The problem is that when I
tried putting the initialisation in the header file immediately after
the class my compiler (g++) rejected it, citing "multiple definition":
g++.exe alphaMain.o alpha.o -o...

I'm having a discussion with my colleagues here on good programming
standards. One thing we haven't agreed on is the use of properties in
classes vs using member variables. Now everyone knows that it is useful to
use a property when it has to do some further action on the data such as
private double salesAvg;
public double SalesAverage
{
set {
salesAvg = value / salesTotal;
}

Perhaps I'm missing something obvious, but I've been curious about one of
the coding practices I see advocated. I'm a longtime C/C++ programmer
trying to learn C#, and I started looking around for coding standards/best
practices.
Several of the documents I've read require that all members be private (or
protected), and the get/set properties be provided for any elements exposed
to the outside world.
In C++ this makes perfect sense,...

I'm still trying to sort out in my head the differences between public and
shared when referring to declaring properties or variables. This is my
understanding:
shared - akin to a 'global' variable for the application. Any other code
within the application can access it.
public - can be shared across the application if instatiated.
Does that sound about right? It seems these are more useful for methods
rather than variables. Most of...

AFAIK there are two ways to expose members of a base class to a derived or
child class:
1. declare the members public in the base class
2. declare them as 'protected' in the base class
Is either of these methods generally recommended over the other? If yes,
why?
Thanks!

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...

The next Access Europe User Group meeting will be on Wednesday 1 May 2024 starting at 18:00 UK time (6PM UTC+1) and finishing by 19:30 (7.30PM).
In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.
Adolph will...

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...
