I read in "Thinking in C++" this code works:
---------
class A
{
static const int b = 1;
};

but it doesn't!
I do something wrong?
I use VC++6 and it returns:

What is the diff. between a singleton class and a static class in C#?

Just a quick architecture question. I'm just looking for discussion,
not a flame war, please.
In the past, I've tended to use a public module for my data layer
functions. Something like:
public module db
Friend ConnectionString As String = ""
Public Sub InitializeDB(ByVal AConnectionString As String)

Hi,
What is the difference between declaring a class as static and delaring
methods as static (class not static)?
Also, when do we use a static constructor?

I've been reading up on them, but I don't quite understand how they
differ in practice. I know how each is implemented, and from C# I
already know what a static method is. But I won't assume that it's the
same in Python. And on top of that, both the class and static methods of
Python seem to do what a C# static method does, so I don't see the
difference yet.
Thanks.

Hi guys
Here's the class I try to compile (see below). By itself when I have a
test.cc file for example that creates an object which is an instance of
the class SpectralProfile, it compiles fine.
1 / Now If I move the getSpectrumAtDistance( const T &dist ) method
definition in SpectralProfofile.cc let's say the compiler says
core/profile.cc:199: error: `kNumBins' was not declared in this scope

Hi Group,
I have a little confusion over the use of static class in C#.
I have a static method in my static class. This method reads an xml
and returns a collection of objects.
This collection of objects can be different for different users.
This method uses some non-static variables which are local to this
method.
Following is my static class:

The output of the following program for me is:
Same
0 1 2
Which is what I want. I just want to confirm this is well defined behavior,
that a static local variable to a class function/method is the same instance
across classes.
#include <iostream>
#include <vector>

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,...
