I read in books that nested class cannot access private members of
nesting class and vice versa unless they are made friends. Somehow, my
compiler is letting my nested class member functions access private
members of nesting class.
template <typename T>
class Container {
// NO friendship given to any other
public:
class ContainerIterator;

CMain Class is the base class that is initialized in main function. CA
Class is the base class that is initialized in CMain::CMain(). CMain Class
is always public while CA Class is always private. I have placed "friend
void CA::Run_A(void)" in CMain Class. CMain::Run() function attempts to
execute CA::Run_A(), but compiler shows an error saying that it is the
violation to access private function.
I don't understand why because friend...

Hi,
I was wondering if there is any way to make two objects of the same
class to be able to access each other's private data, like this:
class A {
public:
void access( const A& a ) {cout<<"a.value="<<a.value<<endl; }
private:
int value;

Hi all,
I read somewhere that private members of some instance of class A are
accessible from another instance of the same class. In other words,
access to private members is done 'on a class by class basis, not on an
instance by instance basis'. I couldn't quite believe it, and tried it
out for myself, and was shocked to see it was true... What is the
reasoning behind this? Why should one Person object be able to see
another Person...

Hello all,
Is there a way to make a class private to the namespace so that other
classes in the namespace can see and use it but noone outside a namespace
can see or use it?
Feel free to send me to links to read, I just cannot seem to find anything
about this, maybe it's not possible.
Thanks in advance, jmy

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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...
