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...

Hi,
I got a little confused on 'instantiation' and 'specialization',
espcially for explicit instantiation and explicit sepcialization. Can
anybody explain the difference?
Thanks a lot!

The following code gives VC++ 7.1 compiler errors C2785 and C2912
template<class U> struct Trait {typedef double result;}
template<class T> typename Trait<T>::result foo()
template<> typename Trait<int>::result foo<int>(); // Line causes errors
Shouldn't this code compile correctly? If so, is Microsoft aware of this bug

Hi,
I'm trying to compile the following code with VC++ 2003.net. ( The real code
is a bit different, but I made a small example that does not make sense, but
it shows the problem )
The code compiles ok with the gnu 3.2.3 compiler and seems to be standard
c++ to me.
Apparently there's a bug in VC++, I'm just checking to see if there is...

I have a class template. Each of the instantiations implements a method
in the class template differently, so I (need?) to use template
speciaization.
My question is this, when writing the specialization, do I need to
implement only the method that is 'different', or do I need to implement
all the methods in the class template?

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. ...
