Hi,
I thought that I understood how C++ allows for the declaration and
defining of variables within an if() statement and how the declared
variable can be used until the end of the major if() block.
if (int a = /*...*/) {
// ...
}
else if (a = /*variable a be assigned*/) {

Hello,
I think I've had JavaScript variable scope figured out, can you please
see if I've got it correctly?
* Variables can be local or global
* When a variable is declared outside any function, it is global
regardless of whether it's declared with or without "var"
* When it is declared inside a function, if declared with "var", it's
local, if not, it's global

of scope and passing data by value and/or by reference but I am confused on

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...

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'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.
