I'm sure there's a good explanation for this effect, but I get rather
a strange output from this little test:
#include <iostream>
#include <list>
int main()
{
std::list<int> int_list;

I have a list of pointers to structs as a private member of a class.
If I call begin() in the same function as I added the data then no
access violation occurs. However, if I try to call begin() in a member
function of the same class I get a memory access violation.
For example:
// this is fine, no error
void CBase::FuncA( void ) {
plugin_info_t *plugin_info = new plugin_info_t;

I need to write an new class derived from the list class.
This class stores data in the list to the disk if an object
that is added to the list is over 1K in size.
What methods of the std stl list class must Ioverride in order for this
to work?

The number of items in my std::list is changed after sorting (using
std::list member function sort). I'm using MSVC6 and the actual (pseudo)
code is posted below. The output from size() is different before and
after the sort. If I remove the sorting (and nothing else), both numbers
remain the same.
int nmerged = 0;
do {
std::list<mum_pair> mregions;

Hi,
There seems to be some functionality missing from the STL.
I am iterating through a linked list (std::list) using a reverse
iterator and attempting to erase certain items from the list. It is
important that I iterate through the list backwards, because the items
in it have to be processed in reverse order before erasing. However,
there does not appear to be an std::list::erase() method defined for
reverse iterators.

Hi,
I've got a class that uses a std::list to store tags that need to be
written out to a device. I've had no problem with the lists in terms
of iterating and reading values. My problem is when I need to pop that
value off the list when I'm done with it.
In this case, I think the iterator is getting "lost" because I pop off
the value it is pointing to at the end of this function. But how do I
pop values off one at a time without the...

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...
