Hi,
Ich have a template class and want to initialize a static variable, that is
available for all objekts of the template class, doesn't matter what
template parameter is used.
Can someone please tell me how it will work!
Thanks a lot!

Hi,
I was curious about how to define static data member of template class.
Should I put the definition in a separate source file or in the same
header file as its template class?
And when this data will be initialized if it is used across many
translation unit, assume that it has constructor and needs dynamic
initialization?
I have...

I have noticed that C programmers put static keyword beside global
variable and global functions in C source codes. I believe that it is not
necessary and it is not the practice in C++. Static keyword is useful
inside struct, class, and function only unless you want to force local
variable to be global variable so static is used.
Do you...

with several sub classes. In runtime I want to create a instance of a
sub class and assign it to a base class pointer. Nothing...

As far I know, static variables are tied to AppDomain scopes. So, every time
an executing code within an AppDomain references a class for the the first
time since the AppDomain was created/loaded, the .NET executes the
assignments done in the class static variables declarations and runs the
static constructor of that class.
So, I expected...

test.cc file for example that creates an object which is an instance of
the class SpectralProfile, it compiles fine.

As we know, the keyword "inline" is a bit misleading because its
meaning has changed in practice. In most modern compilers it has
completely lost its meaning of "a hint for the compiler to inline the
function if possible" (because if the compiler has the function
definition available at an instantiation point, it will estimate whether
to...

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. ...
