When you iterate through a list of objects in a list.
list<object> mylist;
list<object>::const_iterator iter;
object ob;
for (iter=mylist.begin(); iter != mylist.end(); ++iter)
{
ob = *iter;
ob.value = 10;

I have been working on making a constant array available for the clients.
However, it is placing it in the text segment, and external references
result in unresolved references to the array. Taking the const off the
definition solves the problem (the variable is placed in the data segment).
Is this how const globals are supposed to work, or did the linker screw up?
Thanks.

Hello all,
I've been wondering... Why is it that a reference may be bound only to a
const object? If a reference were bound to a non-const object and that
object were modified, what harm could result? A temporary is just as real
of an object as any other. It lacks a name, but that doesn't make it less
real. Class (no pun intended) warfare seems to be alive and well!
Thanks,
Dave

No, this is not a troll, and I am not promoting Java, C-flat, D, APL, Bash,

As long as I write c++ code, I am worry about the
pointer. The more the system is, the dangerous the pointer
is I think.
I must pass pointers erverywhere, and is there a way to
ensure that every object pointered by any pointer will
be deleted and only be deleted once?

I am fine-tuning some last minute things in my c++ allocator lib and was
thinking of ways to manage local references to system objects created with
factory functions. I started to tinker around with using const references to
represent a smart-pointer template that uses intrusive reference counting.
Anyway, here is a short little program that should clearly demonstrate what
I am messing around with:

First in an occasional series.
I'm somewhat experienced in C++, and am using .NET Visual Studio 2005
as the IDE. I'm learning C#.
What I don't like about C#, compared to C++ (all flavors):
1/ no pointers or tracking pointers or handles--this is absurd. I
realise references are by and large like tracking pointers effectively
(does anybody know of any differences--other than pointer arithmetic,

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:

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,...
