I've been programming in python for a few months now - and returning
to programming after a gap of about ten years I've really enjoyed
learning python.
I've just made my first forays into inheritance and operator
overloading (both concepts that I initially found hard to grasp).
I've written a simple config file parser - and I thought I'd
experiment with making the interface easier by subclassing dict and
overloading the __setitem__,...

When we use CollectionBase.List.Remove(object), which methods is used to
compare objects ?
Thanks

Hello,
I am playing around with operator overloading and inheritence,
specifically overloading the + operator in the base class and its
derived class.
The structure is simple: the base class has two int memebers "dataA",
"dataB". The derived class has an additional int member "dataC". I am
simply trying to overload the + operator so that 'adding' two objects
will sum up the corresponding int members.

I am working on a new library for my own use that
would allow me to use SI Units and to convert
them back and forth with ease.
However, While I have been working on operator
overloading, I have come accross a problem:
If I want to be able to simplify units through
operators, I end up with inter-dependant classes.

Hi,
is there a simple way to use operators overloaded in some class for
objects of a derived class?
In my example I have a class Matrix that represents 2x2 matrices, and I
overloaded operator= and operator+ for this class. Then there is a
derived class DiagonalMatrix which represents diagonal 2x2-matrices. Now
I would like to use the operators = and + also for the diagonal
matrices, but the naive way doesn't work:

hi all experts,
i was just thinking about making overloaded operators virtual. i was
wordering what could be the
implications of such scenarios.
i will be thankful if somebody can provide point out some general
issues in making overloaded virtual or point me to some resource
having explaination about the same.

Why can I overload operator== and operator!= separately having different
implementations and additionally I can override equals() also having a
different implementation.
Why not forbid overloading of == and != but instead translate each call
of objA==objB automatically in System.Object.Equals(objA, objB).
This would remove inconsistencies like
myString1==myString2

Here is my problem:
I have a base class A with operator<< defined to take a template
parameter and append the parameter to a output string stream
(ostringstream). I have a derived class B, which inherits from A and
defines a pure virtual output operator<< taking as a parameter an
enumeration type 'Command' (which is defined in B itself). The point
of the 'Command' enumeration is to have a different implementation of
operator<< when...

Hi,
Why does
void* p = new (1024); gives me a compilation error while
void* p = operator new (1024); works. What is the difference between
new and "operator new"? Please help.

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...

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,...

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...
