Hi all,
I have a templated class that derives from a non-templated abstract class.
How do I then cast a base class pointer to a <templated> derived class
pointer in a generalised fashion?
Here's what I'm generally trying to achieve:
I'm building (trying to anyway) a serialization library. Here's my design:

Hi,
I'm learning C++ as a hobby using The C++ Programming Language : Special
Edition by Bjarne Stroustrup. I'm working on chpater 13 exercises that
deal with templates. Exercise 13.9 asks for me to turn a previously
made String class that deals with char's into a templated String class
that uses the template parameter C instead of char. I thought it would
be fairly simple to do this exercise, but I encoutered many errors for

Hi
I'm currently trying to make my old code to compile with
new gcc 3.4.0. It compiles correctly in 3.3.3 so I'm not
sure if this is compiler bug or not.
Code very close to a example below fails to compile
because gcc 3.4.0 complains:
"error: expected a type got 'Y<T>::particle'"

I have a class which needs to accumulate data. The way we get this data
is by calling a member function which returns float on a number of
different objects of different type (they are all the same type for a
given instance of the class, but different types for different instances.)
#include<set>
using namespace std;
template<class T>

Hi,
I want to specialize template member function of a template class .
It is creating some syntax problem ....
Can anyone say how to do it ?
The class is something like this
template<typename T,typename Alloc = std::allocator<T
class CircularBuffer4 {
public:
typedef typename CircularBuffer<T,Alloc>::size_type

I have some templated functions and I want to write a call wrapper
class for it. I
also want to pass the function object from this class to some
functions that will then call the function (forwarded through my class
object to the real function). I've looked around for sources on how
to do this but I can't find anything. How do you do this? I would
also appreciate any references to good sources about this topic if you
have any.

The goal is to make a friend function of an inner template class...
template < typename T >
class Foo {
public:
class Bar {
friend bool operator==(
const typename Foo<T>::Bar& lhs, const typename Foo<T>::Bar& rhs);
};
};

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,...

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...
