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...

hi,
after reading some articles and faq,
i want to clarify myself what's correct(conform to standard) and
what's not?
or what should be correct but it isn't simply because compilers don't
support.
(first i compiled them with g++3.x. ERR means compiler will bark,
otherwise it does accept it. Then the Comeau C/C++ 4.3.3 comes)

Hi,
I have a problem using member functions in derived classes that
override virtual member functions of base classes.
The following pieces of (simplified) code don't work. Can anybody give
me some hints on what might be wrong?

Hi
I'm a little confused here about the lifetime of a static pointer to
member function,
Say,
I declare,define & initialize a static ptr to mem function in the
header file of a class(the class is a helper Singleton class, and is
created & deleted as and when required) - Where does the static pointer
point to when every single instance of the class is deleted.
I presume it'll be dangling pointer- as the code seg to which it's

What am I doing wrong? This code gives a compile error:
'SortedList<T>::insert' : illegal call of non-static member function. I've
tried several variations of this, but keep getting the same error.
template <typename T>
class SortedList
{
public:
void insert( T item); // Write this

The following code snippet shows that VC++ 7.1 correctly compiles a static member function invocation from an Unrelated class, since this static member function is public. I expected to compile the same invocation from a DistantlyRelated class. What actually happened was that the compiler produced:
error C2247: 'A::function' not accessible because 'CloselyRelated' uses 'private' to inherit from 'A'
I'm guessing that the above compiler...

Hi,
Just a simple question: why the compiler doesn't report error when
accessing a private member function inside a function having template
type ?
For example:

using namespace std;

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
