I have two classes, a base class, CBaseClass, and its derived class,
CDerivedClass.
I overload the insertion operator as
ostream& operator << ( ostream&, CBaseClass& );
Then I define an object as
CDerivedClass object;

Hello,
I am trying to figure out how to call an overloaded operator<<
inherited from a base class.
#ifndef PHONECALL
#define PHONECALL

#include "interval.h"

I want to know incase there is any performance difference or overhead
in calling a base class method and a derived class method.
Basically I am talking about simple method that is not overridden nor
virtual. If I declare a method in the base class say M1() and another
in derived class M2(). Then I make a derived class object derived. I
then invoke these:
derved.M1()
derived.M2()

Suppose I have a base class "foo". Another class, "bar" derives from it.
Base class "foo" has a method called "rob_the_liquor_store()", and the
inherited class "bar" overrides this method with one of its own, maybe
specifying the liquor store over on 44th Street and 5th Avenue or something.
Anyway this is what we have so far:
base class: "foo"
|------------method: "rob_the_liquor_store()"

I have a base class with protected members (`Base`). The function `MakeBase()` is a member function of another class, that returns a `Base` object initialized with private members of this class.
Now the thing is, I want to extend the functionality of `Base` class. I do that by inheriting `Base` class by `Derived`, but then I can't use `MakeBase()` function. It all makes sense to me, but I don't seem to find an appropriate solution.
Since I...

Hello everybody!
My problem is somewhat strange since I can't think of any normal situation where one would like to do what I need, but here it goes. I need to somehow cast a base class to a derived class, but from the base-class code. I would need to do something like this:
class Base
{
public Base() { }
public void Convert()

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.

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...
