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?

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

following
two statements.

Hi everyone,
I'm having some trouble getting the correct chain of constructors to be called when creating an object at the bottom of a hierarchy. Have a look at the code below - the inheritance goes like this:

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...

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...
