Hi,
Nested classes only seem to be able to access static members of the
surrounding class :

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;

I've got a class in which I want to implement a property
that operates like an indexer, for the various colors
associated with the class.
For instance, I want to be able to do 'set' operations like
MyClass.MyColors = Color.Green
or, a 'get', such as
Color forecolor = MyClass.MyColors;
I want to use an indexer so I can take parameters, such
as the color type (e.g. "Foreground", "Background" etc.).
With a single member function I couldn't...

I've almost completed building a Model-View-Controller but have run into a
snag. When an event is fired on a form control I want to automatically
updated the "connnected" property in the Model. This works fine if all of
the properties are at the top (root level) of the model but I'd like to keep
them in nested classes to organize them better.
So, for example, part of my data model looks like this (simplified) :
public class MainClass

Hi everyone,
I have a question about referencing a nested class contained within a templated class. Of course the best way to show you is by example. Here's my templated classes:

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...

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,...

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.
