I have a static class member variable as follows:
struct A
{
static void Set (int i) { v = i; }
static int& Get () { return v; }
static int v;
};
int A::v; // define A::v in the cpp file

I know global varaibles should always be avoided. I asked this question
just for deep insight about C++.
If global variables are distributed among different source code files,
what's the initialziation sequence of these varaibles. Say,
Foo g_fooMain in main.cpp;
Foo g_hello in hello.cpp;
Foo g_bye in bye.cpp;
and main.cpp has code
#include "hello.h"

I'd like to discuss about the opportunity to have a global objects
creator that introduces into a general framework
(suited for multithreading) a controlled semantic to manage
globals variables (objects and scalar-types).
In the following example Global is able to create objects of any kind
with and index value attached to. So a Global<0, string> is a unique
string instance object allocated into the system that can be accessed
from any...

I have a problem with static lifetime (order of destruction of statics
within different cpp files). I have a workaround that happens to work
in my case. I'd like to know if this is luck or required to work.
Consider:
class A {
...
static B m_b;
static C& GetC();
};

how do i declare a global variable in c#.net? it's like it want's everything
in classes... there are times when globals are good, like having constants
in a program which apply to several layers/objects/etc...
or does it expect me to create a singleton global class structure?
surely it's not that terrible.

So here's a rather simple question.
Say in an ASP.NET application, I wish to share common constants as static
variables in global.asax (I know there's web.config bla bla .. but lets just
say I wanna use global.asax) ---
Would you declare your static var as ---
public static int x ;

Ok, I've obviously discovered that Global.aspx has been completely changed in
..NET 2.0. However, I haven't figured out how to declare a constant that's
available to any page in my application without having to jump through a bunch
of hoops.
First, let me layout how it worked in 1.1. In the Global.asax, within the Global
class construct, I would simply add something like:
public const string FOO = "foo";

Hi,

I see that static is more restricted in C# than in C++. It appears
usable only on classes and methods, and data members, but cannot be
created within a method itself. Surely this is possible in C# in some
way? Or maybe no, because it is similar to a global variable (with its
scope restricted) which C# is dead against?

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...

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. I'm particularly interested in Zigbee because I've heard it does some...

Hello
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...
