I would like to know in what manner dangling pointers affect the
security of a application developed using C++.What are the loopholes
that are created by dangling pointers and how they could be exploited
by hackers?.

Hello everybody
in a quiz I had a question about dangling pointer:
"What a dangling pointer is and the danger of using it"
My answer was:
"dangling pointer is a pointer that points to some area of ram that's
not reserved by the program. Accessing memory through such pointer is
likely to result in core dump (memory access violation)"

S**t for brains strikes again!
Why did I do that? When I met the clients and at some point they vaguely
asked whether eventually would it be possible to have some people who could
read the data and some who couldn't but that it wasn't important right now.
And I said, 'sure, we can do that later'.
So now I've developed an app without any thought to security and am trying
to apply it afterwards. Doh!, doh! and triple doh!

My experience has always been that you're SOL when trying to safely
detect and stop references to dangling memory (non-null pointers to
free'ed blocks) at runtime (C99, Linux).
Maybe somebody clever has worked this out, though?
(Apologies to those who find the question off topic for CUP or CLC)

What is more secure ?
Encrypt data using php functions before send it to database (mysql), or
Encrypt directly on database, using encryption functions of database
server ?

1.when referenced pointer is not active then it is called dangling pointer.

2.the pointer which does not point to anything is called null pointer.
is NULL macro is a value for null pointer?
3.then what is void pointer?

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,...
