Hi,
Is there an extra overhead in using virtual functions and templates?
Or is is just the same overhead as with regular classes?
Either way, if you'd want to avoid it, will you always end up
with code duplication?
For example: let's say you've got two template specializations, which
differ only slightly... So you put the common behaviour in a

Hello,
templated virtual member functions are not allowed. Now I am searching
for a good workaround for this problem, but I can't find any.
Here's my problem:

Hi
I'd like to create a special cast template function that can be used to
cast a base pointer to a derived one, and uses dynamic_cast if virtual
inheritance is involved, and static_cast otherwise. Unfortunately I
don't know how to properly detect VI.
I've seen a trick for detecting VI, that goes something like:
template <class B, class D>
struct IsVirtualBaseAndDerived

Hello,
I've run into problems with defining a template, which inherits from a
base template and the usage of virtual methods in those. I want to
initialize a member variable depending on which template is created and
I tried to define a virtual method, that's called from the base
template ctor. Here's my example code:
#include <iostream>

A few days a ago I posted my code for a deep copy pointer which
doesn't require the pointee object to have a virtual copy constructor.
I need help with checking that it was exception safe and exception

I got a reply from Bux with his code for a smart pointer with far fewer
lines of code
and more cleaner design, not over engineered like mine.

Hi,
I want a few of my class to overload from a base class, where the
base class contains common functionality. This is to avoid repetition
of code, and may be reducing amount of code in binary, not to get
polymorphic behavior.
None of them has virtual methods, and are self contained (no
destructor at all) thus do not have a chance to have memory error.
Thus the derived classes has additional functionality, not additional
data.

Hello,
My question involves virtual functions and inheritance.
Suppose we have a class structure, that consists of "data" classes, and
"processor" classes. The data classes are derived from BufferBase, and
customized in order to be able to a type of data (of any kind, such as
chunks of audio samples from a sound card). The processor classes are
derived from ProcessorBase, and are customized to handle
BufferBase-derived objects. Each...

Hi to all, I'm facing a problem in a particularly complex inheritance
hierarchy, and I'd like to know what the standard says about it and if my
compiler is correct in what it does.
I have two consecutive layers of diamond-shaped inheritance; the first layer
is declared as using virtual inheritance, while the second one is declared
as *not* using it.
This is what I'd like to have:

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...

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...
