I request some of the people on this group who have good experience
using object-orientation in the field, to please give some good ideas

Hi,
I'm looking for a more concise way than below to extend an existing
interface.
Just imagine that class Interface would have 1000 other members and class
DerivedInterface only needs to add / modify _one_ member. The implementation
shall remain invisible to the application (i.e. main()).
Thanks for any suggestions,

A feature that I find signficantly missing in C# is the ability to write
functions in interfaces that can call other functions of the interface.
Given an interface ISomeInteface the only way we can write a general purpose
function to operate on all objects which implement that interface is through
the following style of declaration (in the following code snippets i is an
interface variable of type ISomeInterface) :

It's dawning on my a lot of my problems with VB.NET is I'm still approaching
it in the same way I've programmed since the late 70's. I've always been
very structured, flow-charted everything, used subroutines, etc. Now I'm
trying to study this new way and I'm getting some terms confused and can
find no clear definition (some even overlap or use two different words for
the same thing, even when they are actually different).

I want to write a Mesh class using half-edges. This class uses three
other classes: Vertex, HalfEdge and Face. These classes should be
linked properly in the process of building up the mesh by calling Mesh
class functions. Let's say they point to each other like this:
class Vertex {
HalfEdge *edge;
};
class HalfEdge {
Vertex* vert;

On Java's Interface
Xah Lee, 20050223
In Java the language, there's this a keyword “interface”.
In a functional language, a function can be specified by its name and
parameter specs. For example:
f(3)
f(3, )

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...

Overview:
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...
