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...

I know how to write "Pointer to Function" inside struct or class without
using static, but I have decided to add static to all functions inside
struct or class because I want member functions to be bound inside struct or
class to become global functions. It makes easier for me to use
"struct.memberfunction()" instead of "globalfunction()" when I have to use
dot between struct and member function rather than global function.
I do not have...

Question: How do friend functions and static member functions differ in
terms of functionality? I mean, neither necessarily needs an object of
the class to be created before they are called and either has access
only to static members of the class (ie. assuming no object of the
class is in scope - neither by arguments recieved nor by local
declarations). Any static member function like this:
//accessing static member i
static void...

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 have idea why most programmers do this?

Hi all,
I've recently been following the object-oriented techiques discussed
here and have been testing them for use in a web application. There is
problem that I'd like to discuss with you experts.
I would like to produce Javascript classes that can be "subclassed"
with certain behaviors defined at subclass time. There are plenty of
ways to do this through prototyping and other techniques, but these
behaviors need to be static and...

Hello,
I learned that there are five kinds of static objects, namely
1. global objects
2. object defined in namespace scope
3. object declared static instead classes
4. objects declared static inside functions (i.e. local static
objects)
5. objects declared at file scope.

Dear Group,
The book of Bjarne Stroustrup in chapter 5.4.4 says the following
"The word static is one of the most overused words in C and C++. For
static data members it has both of the common meanings: static as in
"statically allocated" as opposed to on the stack or on the free store
and static as in "with restricted visibility" as opposed to with
external linkage. For member functions, static has the second
meaning."

I seem to remember that in ANSI C, all static functions should have
their function prototypes listed at the beginning of the file for
better consistency (or something like that). I googled and didn't find
any good explanation about it. Could the experts please give me an
explanation or point me to some link? Thanks!

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...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
