Hello all,
After perusing the Standard, I believe it is true to say that once you
insert an element into a std::list<>, its location in memory never changes.
This makes a std::list<> ideal for storing vertices of an arbitrary n-ary
tree where a vertex contain pointers to its parent / children. These parent
/ child vertices need to stay put if we've got pointers to them somewhere!
Am I correct in my assertion?

Hi All.
I have a question regarding C++ programming language standard. It
is related to standard library, not to the core language.
Is it portable to instantiate template class std::list<> with
incomplete type? I've seen some STL implementations which allow this
and some others that does not. I did not find any mentioning of this
topic in the standard, maybe I searched not enough thoroughly?

Hi,
Suppose I have a list which contains pointers. I want the pointer got
by dereferencing the iterator be a pointer pointing to a const object.
But std::list<const T*>::const_iterator doens't give me this
capability. So I want std::list<T*>::iterator.
However, the container is of type std::list<T*>. How to get
std::list<const T*>::iterator?

The C++ standard says in 23.2.2.4 "list operations" that the
various forms of splice invalidate iterators and references to
the spliced elements. This makes the splice operation a lot less
useful than it otherwise could be. It seems unnecessary to
invalidate these iterators and references, and I am puzzled why
the standard says that it happens. Furthermore, the "merge"
operation that also moves elements from one list to another does...

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,...

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...
