I would like to know if my method to remove list objects is correct in
this small test program. It seems to me that there might be a simplier
way, but I'm afraid I don't know enough about list iterators and how
they are behaving in situations like this.
#include <iostream>
#include <list>
class Test;
typedef std::list< Test* > Tlist;

Hey guys. A new question:
I want to use an STL libarary to hold a bunch of objects I create.
Actually, it will hold references to the objects, but that's beside the
point, for the most part. Here's the question: I want to be able to change
the references (including deleting them). Is there any way to do that
besides using pointers rather than references for the STL library? I'd also
prefer to avoid using const_cast, if it is indeed...

I have written the following code, to test the concept of storing
objects in a vector. I encounter two run time errors:
1). myClass gets destructed when pushed onto the vector
2). Prog throws a "SEGV" when run (presumably - attempt to delete
deleted memory.
Please take a look and see if you can notice any mistakes I'm making.
Basically, I want to store classes of my objects in a vector. I also
have three further questions:

Should dynamic ("expando") properties be restricted to native and
user-defined objects? Or should host objects - such as references to
the browser or a plug-in or to the document and its elements - also
allow them?
Adding (and removing) object properties dynamically is an acceptable
and common practice in JavaScript, and greatly adds to the power and
character of the language. Essentially, an object in JavaScript can be
considered to...

Hello.
I wonder if literal constants are objects, or they're only
"naked" values not contained in any object?
I have read that literal constants may not to be allocated
by the compiler. If the Standard is saying that "object is
a region of storage", I deduce from that that literal constants
aren't objects because they may not be alocated as regions of
storage in the memory.

Hello,
I learned that there are five kinds of static objects, namely
1. global objects
2. object defined in namespace scope
3. object declared static instead classes
4. objects declared static inside functions (i.e. local static
objects)
5. objects declared at file scope.

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

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,...
