I tell C++ Compiler to use level 4 warning instead of level 3 warning so
all variables can be calculated accuracy with no prone error.
It will give you a warning like this.
unsigned short A = 0x8002;
unsigned short B = 0x7FFF;
unsigned short C = 0;
C = A + B; // Warning loss high byte conversion -- 0x8002 + 0x7FFF = 0x10002

Hi all
We all know that C++ is a cleverly conceived multi-paradigm language that
sacrifices very little in efficiency for what it delivers in terms of
type-safety, encapsulation and generic behaviour.
What I want to ask here is - what are the features that people most dislike
about it i.e. that:
- make it more difficult than necessary to implement designs

In MS Visual C++ some code I wrote generated the warning "conversion
from 'int' to 'const float', possible loss of data."
In the process of trying to determine if I could rewrite the code to
eliminate the warning I noticed that the following code did not
generate any warning...

Hi,
I have been trying to use some inventive alternative idioms for infinite
loops in my code, rather than the same old for(;;) and while(1) - this
could be a nice amusing Easter-egg for any future maintenance
programmers!
One of my ideas was this:
unsigned u = SHRT_MAX << 2; // misleading initialization - tee hee!

Hi,
Every time I use a hyperlink field (a field defined as a hyperlink) that leaves the Access Database for either another database or other MS application Access gives me this annoying warning message saying that links should be used only on trusted sites. I would like to turn this message off.
I already changed my security from Medium to Low to avoid the usual other warning messages. I also know about the Set Warnings macro command for...

Hi, I'm using Intel C++ compiler 9 to compiler a project. But, there are
a lot of warning saying like "virtual function override intended....". I
searched old messages in Google groups, someone already talk about this
issue. But I still confused..
This is the simple test code I copied from these messages

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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....

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
