Hello. I posted a question regarding this yesterday. I came up with the
following solution but I am a little hesistant as to this solution having
any side-effects that I am not aware of. The solution seems to work though.
Please let me know if this is okay or if I need to modify something here.
Thanks !!!!

Hello ladies and gentlemen.
I have a relatively simple problem that I've been unable to solve.
In the interest of learning C++, I've decided to write a simple game.
The basis for the game is 8x8 board (think chess). I decided to
implement iterators so it'd be easy to analyze the board position etc.
Basically I have the following hierachy:

Recently I have had to use a value type for a complex structure because I
don't know how to override the = operator. Can the operator ever be
overloaded? Or can inheritance be used with value types?

Hello,
recently I wrote a little class which has to wrap two different type of
data, showing the same external interface.
I used operator overloading, but the same result I could eventually
obtain with two classes derived from an abstract base class containing
only the interface functions. So, when it's worth to use overloading
mechanism instead of abstract/inherited?

I'm having difficulty with overloading ==, and it's making my
brain melt - can you help...? What I want to have is:
1) A base class A with virtual operator== defined (no problem)
2) A class B derived from A with operator== overridden (again, no problem)
3) Pointers A* b1, b2 which may actually point to instances of B, where I
can call (*b1)==(*b2) and have it use the overridden form of == found in
B.
Having written this all out I'm...

I am getting a compiler error that I can't well explain or even
understand the origin of (though I boiled it down close...). Below is
a bare-bones example.
What I am doing is defining the increment operator in a class and then
defining a derived class and using the derived class. When I try to
use the increment operator on an instance of the derived class (as an
instance of the derived class, not when used as an instance of the base...

Hi there,
i am implementing a Point and Vector class and found that they have some
things in common. Therefore i introduced a common parent class called
ndimobj, that hosts an array of n values, offers some constructors and
the following operator

Are static method inheritable under csharp rules, if so how can they
be used? Can they be virtual?
They reason I am asking is because operators are static, and I don't
understand how can we apply operators to base and derive classes
simultaneously?

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

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...
