Hello,
I have the following code, with a basic class having a constructor and
destructor. in the main section, I create a static pointer to the
class. My question is regarding the destructor. If I dont explicitly
delete the pointer, the destructor is called. However, I expected that
even with out explicitly deleting it, the destructor would be called
when the program ends.
#include <iostream>

Hello,
I've been trying to implement smart pointers in C++ (combined with a
reference counter) because I want to do some memory management. My code
is based on the gamedev enginuity articles, various books and ...
whatever I could find on the subject :-)
I'll leave out the reference counter part because its pretty basic, but
my reference counter class is called xObject. My smart pointer class is
called xPointer.

Hi,
I'm just reading about smart pointers..
I have some existing C code that I would like to provide wrapper classes
for. Specifically, I would like to provide wrappers for two stucts
defined as ff:

Hello.
I have written a simple reference-counting smart pointer class template
called RefCountPtr<T>. It works in conjunction with another class,
ReferenceCountable, which is responsible for the actual counting. Here
is the latter's definition:
// --- Begin ReferenceCountable.h ----------
class ReferenceCountable

Handle Classes
Handle classes, also called Envelope or Cheshire Cat classes, are part of the Bridge design pattern. The objective of the Bridge pattern is to separate the abstraction from the implementation so the two can vary independently.
Handle classes usually contain a pointer to the object implementation. The Handle object is used rather than the implemented object. This leaves the implemented object free to change without affecting...

I'm using reference counted smart pointers in a small project and it's
a breeze, but I'm running into a problem which I don't know how to
approach.
Consider something like this:

A() {}

I asked a long time ago in this group how to make a smart pointer
which works with incomplete types. I got this answer (only relevant
parts included):

Data_t* data;

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...
