Is there any difference between declaring a variable at the top of a method
versus in the code of the method? Is there a performance impact for either
choice? What about if the method will return before the variable is used?
I'm trying to get an idea of whether the .NET compilers for VB.NET and C#
will move all variable declaration to the beginning of a method or whether
they will allocate the memory as it is needed by the method to...

Gurus,
If a static variable is defined in a class what is the scope of the variable
resolved to for it to remain 'static'? For instance, lets say I create a
class library assembly that is strongly name which contains the class where
the static variable is defined. This library can be referenced by multiple
projects. I am fairly sure the static variable does not survive across the
application boundry but does it within the application...

VARIABLE SCOPE IN JAVASCRIPT
LEVEL: BEGINNER/INTERMEDIATE (INTERMEDIATE STUFF IN )
PREREQS: VARIABLES
First off, what the heck is 'scope' (the kind that doesn't help kill the germs that cause bad breath)? Scope describes the context in which a variable can be used. For example, if a variable's scope is a certain function, then that variable can only be used in that function. If you were to try to access that variable anywhere else in...

We often get questions on this site that refer to the scope of variables and where and how they are declared. This tutorial is intended to cover the basics of variable scope in VBA for MS Access. For the sake of brevity I am sticking to common usage.
Wherever the term procedure is used in this tutorial it actually refers to a subroutine or function.
Definition of Scope
The scope of a variable where this variable can be seen or accessed...

Can we declare extern variable as static?
What will be the scope of the variable then? What if we change the
value of the variable in some other function?
Also can someone tell me that if we can declare the global
variable...and it is having scope throughout the file then what is so
different in extern variable???

When I control if I print messages, I usually use a global variable
"int silent". When I set "-silent" flag in my command line
parameters, I set silent = 1 in my main.c.
I have many functions that may print some messages.

{
if (!silent)

Dear all,
Do you know whether ANSI C (or some other dialects) support the
following:
* a variable name coincides with a type name,
* a structure/union field name coincides with a type name
in the same file (.c + all relevant .h's)?
e.g.

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,...
