Does using multiple inheritance introduce any more performance overhead than
single inheritance?

It seems no pattern defined by GoF takes advantage of multiple
inheritance. I am wondering if there is a situation where multiple
inheritance is a necessary solution.
When coding in C++, should multiple inheritance still be avoided?
If yes, why multiple inheritance is introducted into C++?

I want to know why C# doesnt support multiple inheritance? But why we can
inherit multiple interfaces instead? I know this is the rule, but I dont
understand why. Can anyone give me some concrete examples?

why doesn't .NET support multiple inheritance?
I think it's so silly!

Some Sr. colleges and I have had an on going discussion relative to when and
if
C# will ever support 'true' multiple inheritance.
Relevant to this, I wanted to query the C# community (the 'target' programming
community herein) to get some community input and verify (or not) the
following
two statements.

Hello!
My question is about calling this method CollectData below but I get a
compile error that I shouldn't have because the type parameter is correct.
The compile error is the following:
C:\PK\Development\Products\UTCAS\4.0\SRC\MeltPracApplication\Dialog\Composit
ionForm.cs(942): Argument '1': cannot convert from 'ref
MeltPracData.MeltPracDataComposition' to 'ref
MeltPracCommon.IDialogPostData'

I have read that using templates makes types know at compile time and
using inheritance the types are first decided at runtime. The use of
pointers and casts also indicates that the types will first be know at
runtime.
But is there some strict definitions that defines runtime code and
compile time code that can be used in general?

I just read a blurb in MSDN under the C++ "ref" keyword which states that:
"Under the CLR object model, only public single inheritance is supported".
Does this mean that no .NET class can ever support multiple inheritance. In
C++ for instance I noticed that the compiler flags an error if you use the
"ref" keyword on a class with multiple base classes. This supports the above
quote. However, under the "CodeClass2.Bases" property (part...

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,...

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...
