Hello Experts!
Assume I have a class called SphereClass as the base class and a class
called BallClass that is derived from the SphereClass. The copy constructor
initialize the left hand object in this case object b2 below. It also
initialize subobject from class SphereClass.
The BallClass copy constructor looks like this.
BallClass::BallClass(const BallClass& bc) : SphereClass(bc)

AFAIK there are two ways to expose members of a base class to a derived or
child class:
1. declare the members public in the base class
2. declare them as 'protected' in the base class
Is either of these methods generally recommended over the other? If yes,
why?
Thanks!

Hi,
finally giving php 5 a go, and going over the new approach to classes.
Can someone clarify the public, private and protected to me?
I quote the php manual: "The visibility of a property or method can be
defined by prefixing the declaration with the keywords: public,
protected or private. Public declared items can be accessed
everywhere."

In an article on the safe bool idiom
(http://www.artima.com/cppsource/safeboolP.html), Bjorn Karlsson gives
the following code (slightly modified):
class safe_bool_base {
protected:
typedef void (safe_bool_base::*bool_type)() const;
void this_type_does_not_support_comparisons() const {}
safe_bool_base() {}

Before going to that i want to say few thing on serialization :
Serialization is the process of converting an object into a form that can be readily transported. For example, you can serialize an object and transport it over the Internet using HTTP between a client and a server. On the other end, deserialization reconstructs the object from the stream.
XML serialization serializes only the public fields and property values of an object...

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...

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...
