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
I'd like to implement some kind if type traits myself, but I have to
support broken compilers (like visual studio) that do not support
Partial Specialization.
My first shot was something like this:
----8<---
typedef char IsPODForListArrayTrue;

template<typename T> struct A{}; //line 1

VC6.0 compiler results for the above:
at line 3:
error C2989: 'B<struct A<T> >' : template class has already been
defined as a non-template class

I would be grateful if someone could point out if I am understanding
correctly and suggest ways to improve. Sorry for the long message and
I hope you will kindly bear with it. I have to make it elaborate to
make sure my questions are clear enough.
Let's say I need to write a function whose logic is same for all types
(T) except in the case of T * (including const T *). Furtheremore ,
the function needs to be written differently for...

I've never understood the rationale of allowing partial, but not
explicit specialization for classes at non-namespace scope. Ie.:
struct A {
template <typename T1, typename T2>
struct B {};
// this is not allowed:
template <>
struct B<int, float> {};

I am learning template programming. When testing the partial

I tried a couple of compilers, and both gave errors compiling this:
template <bool fin, typename T>
T foo(T val);
template <typename T>
T foo<true, T>(T val) { return(val); }
But both gave no errors compiling this:

Hi,
I have a template function for which I use SFINAE to restrict one of
the parameters. Then I also have a partial specialization of this
function.I would like to provide an explicit instantiation of the
partially specialized version, but my compiler (VC8) complains because
it fails the SFINAE version.
I just realized as I was typing this that I'm using partial
_function_ specialization. I'm sure I remember reading somewhere that

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...

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...
