Hi,
I have a design problem about which I am thinking now for a while and still
couldnt find any help in deja. What I need is something like a virtual
function template. I know that this is not possible, so I need "something
like" a virtual function template. I read in some threads that there is a
workaround using the visitor pattern. I read therefore in the book "Modern
c++ Design" about this pattern, but couldnt find any help to my...

Can anyone explain how I can make the following function accept an
default arguement for the last parameter, which should be an optional
functor?
template <typename T, typename FUNCTOR>
void bsort(T * si, T * ei, FUNCTOR cmpfunc)
{
int k = 0;
for (T * i = si; i < ei - 1; i++, k++)
for (T * j = si; j < (ei-k-1) ; j++)

As a self-exercise, I am trying to write a generic Priority Queue,
which would store any type and and accept any user-definable
"priority" function.
After much tinkering, I came up with something like below:
class PMinimum {
public:
template <typename T>
bool operator()(const T & a, const T & b)

Can anyone kindly provide an explanation as to why the compiler does
not "see" the function template in the contrieved code below?
I think the argument deduction fails but can't figure out exactly what
the problem is. Is it related to the fact that a nested class is
involved?
#include <iostream>
using std::cout;

Hi All,
I used an article on XSLT and XML and creating a TOC written on the MSDN
CodeCorner.
ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.1033/dncodecorn/html/corner042699.htm
However, it did'nt quite answer all my questions.
How would one create a 3 level TOC when each item level / node was
differently named (They used Template match and for-each, but the template
match worked as on a 3 level structure they usedf the same named xml...

Hi everyone. A very simple question. I would like to know what is
better in terms of performance. I want to use a simple function to
obtain the minimum of two values. One way could be using a macro:
#define min(a,b) ((a<b)?a:b)
I thought that another way could be to use a template function:
template <class T>
T min<T a, T b>

Hi,
I am looking for a way to achieve the following. I've tried a couple
of things, but they all ended up being too complicated:
I have a templated class A. I want another class B to be able to call
a method defined in A's base class which at runtime determines the
template parameters (I know ahead what is allowed) and calls a
templated member function B with A's template parameters.

This is from a thread that I posted on another forum some days ago.
I didn't get any response, so I'm proposing it in this ng in hope of
better luck :)
The standard explanation is that pointer to functions are hard to
inline for the compiler, and so you won't be able to avoid function
call overhead.
This is an important aspect when you are calling a function very
frequently for evaluation reason: think of the problem of performing...

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...

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...
