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?

Hi,
I wrote an article that may be of interest to some people in this
newsgroup. It explains the memory (object) layout for multiple and
virtual inheritance. The article can be read at
http://www.phpcompiler.org/doc/virtualinheritance.html
If anyone has any corrections or suggestions for improvements, I'd
appreciate it.

Guys, I have this situation: the class C is defined as follow:
class C: public A, public B {...};
Now when I create an object of class C, I can see that the compiler (VS
8.0) decides to layout the memory of this object so that the fields of
class B come before the fields of class A. I always thought the layout
is defined by the order of inheritance. Was I wrong?
Thanks.

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:
Shape
|
+-- Ellipse
|
+-- Circle

Hello,
I've been reading Effective C++ about multiple inheritance, but I
still have a few questions. Can someone give me some help please?
First, it is said that if virtual inheritance is used, then "the
responsibility for initializing a virtual base is borne by the most
derived class in the hierarchy". What does it mean? Initializing
base class is usually done automatically by the compiler, but a
derived class can invoke the base...

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,...

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....
