I am trying to implement inheritance but I am having a difficult time with some concepts.
What I am trying to do is have a Child object inherit from the Parent, and when you set a property value at the Parent level, I want all of the children to see this change. Likewise, when I set a Parent's property value in the child object, both the parent and all of the children see the change.
Maybe what I am trying to do is not "inheritance" after...

I'm attempting to write a program with several child classes derived from a
single parent class. The parent class has a couple of variables that need
to be present in each of the child classes. However, I need the objects
created from each of the derived classes to share these variables with other
objects of the same class but not with other objects of the other derived
classes.
Let me try to clarify with an example:...

Hi!
If I've a vector filled with abstract classes, can I push in it the
derived classes too? Even if derived classes have new methods?
I've done some experiments, and it seem I can push the derived classes,
but I can use them only calling the methods declared in abstract class
(the new methods declared only in derived classes return an error).
Please take a look to my code (hey, this is not an homework!

During construction of an object "parent", if you create a subobject
that stores a pointer to the parent (through the "this" pointer), will
that pointer be valid when the subobject is later called?
class Parent
{
Parent::Parent() { child = new Child( this) };
Child *child;

Group,
I'm trying to understand the problem with the following code. The
problem I get is associated with the line "int fmt = format(); " at
the bottom of the line. The error I get says that "format does not
take 0 arguments". It appears that the version of "format" that
returns an INT is NOT available to a derived class. Please notice that
there are 2 version of the format function.
Is this correct behavior? I get the same error...

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...
