I have two questions which are very similar:
Is it possible to return an object in C++. Below is part of my code
for reference however I am more concerned about the concept. It seems
like the function below is returning a pointer to pointers who are
GUID. I am trying to write a wrapper to use in my VB code and what I
would prefer to do is be able to return an array of GUID. I remember
(not sure) that the concept of arrays does not really...

Is there any possibility of invoking the member functions of a class
without creating an object (or even a pointer to ) of that class.
eg.

Hi everybody,
I read Scotte Meyer's "Effective C++" book twice and I know that
he mentioned something specific about constructors and destructors that
was related to the
following error/warning: "error: invalid use of nonstatic data member "
However, he did NOT mention this error in the book explicitly.It
happens always in the constructor when you try to initialize some data
members in the constructor and try to accsess other data...

I have a very specific question about a language issue that I was
hoping to get an answer to. If you allocate a structure that
contains
an array as a local variable inside a function and return that
structure, is this valid?
As shown in the code below I am allocating the structure in the
function and then returning the structure. I know if the structure
contained only simple types (int, float) this will work without
problems as you...

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,...
