I will present very long code, hope someone will read it all, and teach me
something like tom_usenet.
This question comes to me when i read <<Think in C++>> 2nd, chapter 10 ,
name control, section "Static initialization dependency". There is a
example to show how to solve the prolem involved with a technique first
poineered by Jerry Schwarz while creating the iostream library (because the
definitions for cin, cout, and cerr are static...

For a singleton class utilizes by ASP.NET 2.0 page processing:
When initial instantiation is performed during the initial call to the
retrieve instance method (let's call the method "getInstance()"), an
instantiated object of the class is assigned to the class' internal static
reference to that an object of itself (let's call the reference
"uniqueInstance")
Does that uniqueInstance have global scope in the context of page processing
?

Hello everybody, my first message on this forum. I tried to solve my issue by reading other similar posts, but I didn't succeed. And forgive me if this mail is so long.
I'm trying to achieve the following (with incomplete succes): I want in a given namespace Parameters a list of "initializers" (which are objects derived from a simple interface that can be implemented anywhere, and are used to define which parameters the program will take at...

Hi,
I had a problem in my code recently which turned out to be the 'the "static
initialization order fiasco"' problem
(<http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.12>)
The FAQ section describes a solution using methods returning references to
static objects.
But consider:

The way I understand the startup of a C++ program is:
A.) The stuff that happens before the entry point.
B.) The stuff that happens between the entry point and the calling of
main().
C.) main().
So, if the above is OK, does static initialization occur during A or B? What
happens during A?

I don't know what to think of the following..
(from the dietlibc FAQ)
Q: I see lots of uninitialized variables, like "static int foo;". What
gives?
A: "static" global variables are initialized to 0. ANSI C guarantees that.
Technically speaking, static variables go into the .bss ELF segment,
while "static int foo=0" goes into .data. Because .bss is zero
filled by the OS, it does not need to be in the actual binary. So it
is in fact...

I have the following problem in a C project (but that also needs to
compile with a C++ compiler). I'm using a virtual function table, that
looks like this in the header file:

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...

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...
