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...

The C++ book I have to hand (Liberty and Horvath, Teach yourself C++
for Linux in 21 Days--I know there are better) states that "static
member functions cannot access any non-static member variables".
However, this doesn't seem entirely correct. It also doesn't mention
whether static member functions can access protected and private
member data and methods (and I couldn't spot this in the FAQ).
I have a class row<Row> which derives from...

On Solaris, using the Sun compiler, I get annoying warnings from the
following code. The problem is that I am passing a C++ member function
pointer to the C library function qsort. Is there a solution?
Declaring the function extern "C" fails, because linkage declarations
must be made at file scope.
#include <stdlib.h> //for qsort
template <class T>
class Sorter

Just trying to learn some things about templates. Was wondering how
boost::tupple really works, but the headers were a bit confusing to me.
I know you get do something like the following, just want to know how
it works with the overloading of get<>().
boost::tupple<int,doubletup(1,2.0);
double d=tup.get<2>(); // equal 2.0

Hi,
When modifying a data member in a class declaration, the static keyword
specifies that one copy of the member is shared by all instances of the
class.
Does that mean that the address of the data member is the same for
every instance of that class? I would expect so, but I noticed
something that makes me doubt a little.

Hi guys
Here's the class I try to compile (see below). By itself when I have a
test.cc file for example that creates an object which is an instance of
the class SpectralProfile, it compiles fine.
1 / Now If I move the getSpectrumAtDistance( const T &dist ) method
definition in SpectralProfofile.cc let's say the compiler says
core/profile.cc:199: error: `kNumBins' was not declared in this scope

Hello world, I'm wondering if it's possible to implement some sort of
class/object that can perform mapping from class types to strings?
I will know the class type at compile time, like so:
const char *s = string_mapper<thetype>();
However I do not know the string to be associated with the type at
compile time, and will need a way to set up the mapping, to be created
at run time, possibly like so:
void foo(char*...

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,...
