I'd like to overload 'comma' to define a concatenation operator for
integer-like classes. I've got some first ideas, but I'd appreciate a
sanity check. The concatenation operator needs to so something like
this:
1) e = (a, b, c, d); // concatenate a,b,c,d into e
2) (a, b, c, d) = e; // get the bits of e into a,b,c, and d
For example, in the second case, assume that a,b,c,d represent 2-bit
integers, and e represents an 8-bit...

Hello. I am trying to learn how operator overloading works so I wrote
a simple class to help me practice. I understand the basic opertoar
overload like + - / *, but when I try to overload more complex
operator, I get stuck.
Here's a brief description what I want to do. I want to simulate a
matrix (2D array) from a 1D array. so what I have so far is something
like this:

I have defined a number of custom stream buffers with corresponding in
and out streams for IO operations in my program, such as IO::output,
IO::warning and IO::debug. Now, the debug stream should be disabled in a
release build, and to do that efficiently, I suppose I need to overload
the << operator.
My current implementation of the stream in release mode is posted below.
Everything works fine for POD type like bool and int, but the...

I have a problem with a C++ code I can't resolve, or better, I can't see

Here's an excerpt of the incriminated code:

I need an example of a managed overloaded assignment operator for a
reference class, so I can equate two classes A1 and A2, say called
ARefClass, in this manner: A1=A2;. For some strange reason my C++.NET
2.0 textbook does not have one. I tried to build one using the format
as taught in my regular C++ book, but I keep getting compiler errors.
Some errors claim (contrary to my book) that you cannot use a static
function, that you must...

Yes, hi
How to write "operator +" and "operator =" functions in a class with
a defined constructor? The following code demonstrates that I don't
really understand how to do it... I think it has something to do with
the compiler calling the destructor twice. Could someone point out
where I go wrong?
P.S.: The error it gives is "Debug Assertion Failure ....." (at run
time)
P.P.S: Everything else works just fine (without the use of...

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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,...

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...

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.

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...
