Pythons internal 'pointers' system is certainly causing me a few
headaches..... When I want to copy the contents of a variable I find
it impossible to know whether I've copied the contents *or* just
created a new pointer to the original value....
For example I wanted to initialize a list of empty lists....
a=, , , , ]
I thought there has to be a *really* easy way of doing it - after a

This doesn't work:

Hi all,
I dont know whether this question has been raised before or not.
Nevertheless, here is my question...
I have a structure of around 255 elements of the same type, say int.
I have an array of this structure of around 100 elements. I want to
initialise all the 100 elements of this array (and the 255 elements
too) to some specific value (a non-zero value). Is there any way of
doing it without using loops?

This seems like a fairly basic thing to want to to, but as far as I can
tell, it's not possible. Can anyone help?
I have a class 'Foo' and I want to call the constructor with a particular
(identical) value for each object in an array of 'Foo's:

I always used to initialise variables at declaration, then a couple of
colleagues started telling me it was bad practice and that the compiler
should be left to spot the use of uninitilised variables and hence
possible bugs.
Your thoughts on the above would be welcome (as an aside), but my main
problem follows.
Now I've recently upgraded to gcc 4, and I find I'm missing the compiler
warnings I used to get on gcc 3 regarding...

I'm trying to write some code which:
1. Finds all modules in a plugin directory
2. Imports those modules
3. Creates an instance of each object defined in the module (each module
will contain exactly 1 object, which is a subclass of 'Plugin')
The closest I've come so far is with something like:

Hi,
Im trying to migrate from programming in Matlab over to C. Im trying
to make a simple function to multiply one matrix by the other. I've
realised that C can't determine the size of a 2d array, so im
inputting the dimensions of those myself.
The problem is that the output array (C=A*B) has as many rows as A and
as many columns as B. I would think of initialising C with:

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...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
