Hello all,
I have recently been porting code from Linux to cygwin and came across
a problem with static const class members (discussed below). I am

DLL). It only occurs when the static const...

Hey
Im new to c++, so bear with me. I'm used to other OO languages, where it
is possible to have class-level initialization functions, that
initialize the CLASS rather than an instance of it. Like, for instance
the Objective-C method:
+(void)initialize
Which has the following characteristics: It is guaranteed to be run

Hello everyone,
I have a Packet class I use to send packets over the Internet. All the
packets sent in a session are supposed to share a common random ID.
I figured I'd use a static const member inside my class.
class Packet
{
static const int session_id;

Hello,
I was told that if I declare a static class constant like this:
class A{
static const int x = 10;
};
then the above statement is a declaration rather than a definition.

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,...

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...
