Hello.
I am reading the book written by Bjarne Stroustrup called " The
C++ Programming Language - Special Edition" and
had a doubt which a think is really important to distinguish between
the main features of modules, namespaces, and
User-Defined types. The text above was copied from page 31.

When it is being said that, "value types are created on the stack or inline as part of an
object". If a value type is created in an object, and that object is being
called, the value type in that object, is still created on the stack, I
would say, so I don't understand this inline business. Apart from the fact
that it is my understanding that "inline" as it exists in C++ doesn't exist in C#. Could someone please shed some light on this...

I have created a structure with five fields. I then create an array of this
type of structure and place the structure into an array element. Say index
one. I want to assign a value to field3 of the structure inside the array.
When I try this, an error about late assignment appears. Is it possible to
assign a value to a structure field that is in an array?
I'm currently getting around the problem by creating a new structure, assign...

Structs are value types, strings are ref types. If you have something
like this:

I'm curious about the differeng behavior of the "new" keyword when dealing
with value versus object types. If I'm correct, when I do:
dim x as integer
There's no need for "new" to be called since this "value" type is all set to
go. Is this because value types are stored on the stack so the memory
initialization is already taken care of?
Now, when dealing with an object type, it seems you do need to use the "new"

Hi.
I am a little confused about the difference between a "value class" and a
"ref class".
I have the following code sample that shows the definition of a value class
and of a ref class and each is instantiated twice - one on the stack and one
on the managed heap. I see no difference between the two, at least not in
the way they are used. Can someone explain the difference, please? Thank
you.

I'm reading a book on C# and it says there are 4 ways of passing types:
1. Pass value type by value
2. Pass value type by reference
3. Pass reference by value
4. Pass reference by reference.
My interpretation:
1. Essentially pushes the value type on the stack

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,...
