Hi,
I have a class with several member variables that should be initialized
according to user input before an object is instantiated. Using a static
variable is required here.
But, I would like to have each object of my class have unique values of
these variables, because the values may be different depending on some other
factor in the...

Dear Newsgroup,
I'm somehow confused with the usage of the static keyword.
I can see two function of the keyword static in conjunction with a data
member of a class.
1. The data member reffers in all objects of this class to the same data
Or in other word by using the static keyword all objects of one class
can share data. (This is...

Why is it allowed in C++ to call a static member function of an object
through an instance of that object? Is it just convenience?

So here's a rather simple question.
Say in an ASP.NET application, I wish to share common constants as static
variables in global.asax (I know there's web.config bla bla .. but lets just
say I wanna use global.asax) ---
Would you declare your static var as ---
public static int x ;

A static data member can be of the same class type as that of which it
is a member. A nonstatic data member is restricted to being declared as
a pointer or a reference to an object of its class.
And I haved used the sizeof operator to test a class which has a static
data member, the class size is all the nonstatic data member except the...

Hi -
I've got a class that contains static member functions alone, all of
whose arguments are passed by reference as shown below:
class MySpiffyClass{
// no constructor, destructor or variables, just static members
static void FirstFunction( args & );
static void SecondFunction( args & );
static void ThirdFunction( args & );

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. ...
