Coming from the C++ world I can not understand the reason why copy
constructors are not used in the .NET framework. A copy constructor creates
an object from a copy of another object of the same kind. It sounds simple
but evidently .NET has difficulty with this concept for some reason. I do
understand that .NET objects are created on the GC heap but that doesn't
mean that they couldn't be copied from another object of the same kind when...

Hi,
A default copy constructor is created for you when you don't specify one
yourself. In such case, the default copy constructor will simply do a
bitwise copy for primitives (including pointers) and for objects types call
their default constructor.
Any others points i should know?

Dear all,
So passing and returning a class object is the time when to include the
definition of the copy constructor into the class definition. But if we
don't call by value or return by value, we do not need to use the
copy-constructor. So depending on the above reasoning I can avoid call
by value and return by value for class objects, this bypasses the
problem or it seems to me like that.
Could any one give me some simple examples...

Dear All,
I am wondering how the default copy constructor of a derived class
looks like. Does it look like
class B : public A
{
B(const B& right)
: A(right)
{}

A simple program with operator overloading and copy constructor:

From my understanding, if you declare any sort of constructors,
(excluding copy ctor), the default will not be included by default. Is
this correct?
class Foo{
public:
Foo(int); // no Foo() is included, i believe.
};

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...

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...
