Hi everybody,
I would really like some help explaining this apparent discrepancy,
because I really don't get it. Here is the snippet:

void foo(int const&);

I would like to propose the following changes to the C++ Standard,
the goal of which are to provide an improved ability to specify
the constraints on type parameters to templates. Let me say from
the start that my knowledge of compiler implementation is very
limited. Therefore, my suggestions may have to be rejected
because they are difficult or impossible to implement.
The proposal is based on the concept of "type similarity". Type...

I have heard that it is possible to use classes + template magic to
make standalone functions (or maybe just a functor which acts like a
function) which can accept variable length arguments without using the
elipse. For example, a funciton could take in 1 known type, then a
variable list of other parameters:
ReturnValueClass rvc = someFunction("Some known type", 1, 0.2,
"string");
ReturnValueClass rvc2 = someFunction("Some known type...

Hello all,
my question is basically wheather it's possible to
have nested templates .. I mean the following
if there are one templ. class and one global templ. function
is it possible to specialize the function for say <int>
but this for all possible classes (from class template)
the code is here

Below is a problem I am having with templates. I am trying to use a
template to avoid having multiple class methods that differ only in the
return type of the pointer. I have tried putting in another parm of the
typename to guarantee the uniqueness of the parm list but it didn’t
help. I am getting undefined externals from the linker, one for each
elemental type. Any ideas would be appreciated.
Thank you,

Hi everyone,
I've been using templates for a while, but I'm not at full power yet
(knowledge=power) ;). Does anyone know where I can get information on
this 'new' template usage?
template<a (b, c, d)>
Does one define it like:

Hi all,
I have a slight problem with the usage of function templates. It shoud
be really easy for you guys to explain me what's wrong.
I have one base class and 2 derived classes:
/*code*/

template <typename Tstruct GrayImage : public Image<T{...};

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...

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...
