Hi
Template partial specialization always seems like a fairly
straightforward concept - until I try to do it :).
I am trying to implement the input sequence type (from Stroustrup
section 18.3.1, 'Iseq'). I want the version for containers that he
gives, but also to provide a specialization for construction from a
pair<It,It> (eg because that is returned by equal_range()).

Hi,
If you've got a template class with lots of methods,
and then you've got a type which works with the template,
except for one method...
What you need to do there is specialize the template for your
type. However, this requires you to copy the whole template, and
change the method, which leads to code duplication...
If there's only 1 template parameter, one can specialize the method

Hi group,
I have a problem with partial template specialization. In the code
below I have a template struct Music with one method, play(),
and three kinds of music, Jazz, Funk and Bach. When I specialize
Music<Bach>, I expect that the original play() method is available
in the specialization, but it is not. How can I fix this?

Hello,
I was experimenting with class templates and specializing member
functions and came across a simple problem which I can't figure out.
I have a simple class C with 2 template member objects, and a function
print() that prints the value of these objects. I defined a
specialization of print() for C<string, char> which is called
correctly. Then I wanted...

Hello all,
Consider this function template definition:
template<typename T>
void foo(T) {}
If foo is never called, this template will never be instantiated.
Now consider this explicit instantiation of foo:

Hello.
I have written the following program and am curious why it prints "1" "2".
What are the exact effects of explicitly providing function template
parameters at the call? Is the second assign() function really a
specialization of the first assign() or is it an assign() overload?
Thank you.

Hi,
I would like to write a template class Polygon<VertexTypthere vertex
typ can be eigther a pointer or a value typ.
It has an attribute:
std::vector<VertexTypvertices;
And a methode:
VertexValueTyp& vertex(int i);
that dereferences vertices internally in case VertexTyp is a pointer

i have a template as shown
template<typename Sclass Indexer{};
i want to have a specialization for std::vector both const & non const
version.
template<typename T,typename Aclass Indexer<std::vector<T,A {}
matches only with nonconst version. anyway to match it for both? and
get if it is const or nonconst?
Actually i want 2 specialization, one for std::vector<T,Aconst & non
const other for std::deque<T,Aconst & non const.

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...
