Please skip to the last paragraph if you are in a hurry.
Some of the integer variables in my application will need to hold values
bigger than 2^32-1.
Others won't need to be that big. Time and space efficiencies on
run-of-the-mill (read: 32 bit) microcomputers are important.
I want to use some layer of abstraction comparable to C99's stdint.h so
that my variable declarations specify the number of bits.

Hello all,
I have a delima. I have 8 5bit numbers that I need to pack into one (or
more) variables. They then must be written (exactly 40bits (5Bytes)) to a
file and have the ability to be put back into memory and then get the 5bit
numbers out again. As I am not by any means proficient in C++ (still
learning) I don't know how to go about doing this correctly. The way I was
planning to do it is as follows:
1. create a character array...

I am facing this problem....
I have to define a structure at runtime as the user specifies...
The user will tell the number of fields,the actual fields...(maybe
basic or array types or multiple arrays,etc)
I do not understand how to define the structure at run time.i.e.what
fields it will contain.

Hi,
Does C# support struct bit definitions. For example is there a way to
declare somethink like this C/C++ Code:
struct CELL { // Declare CELL bit field
unsigned short character : 8; // 00000000 ????????
unsigned short foreground : 3; // 00000??? 00000000
unsigned short intensity : 1; // 0000?000 00000000
unsigned short background : 3; // 0???0000 00000000
unsigned short blink : 1; // ?0000000 00000000

I often peruse source that use memory mapped registers as a
configuration and/or command and status interface between embedded
software and FPGA logic. In doing so you're given a register name
accompanied by descriptions and a location in memory for reading/
writing data.
For ex:.
Revision Register - Location 0x0000

Hi ppl
A simple question! I'm afraid it can be a bit silly, but I'm not an experienced programmer
How does a 32 bit windows OS, comes with a calculator where you can sum really big numbers, over the limit of 32 bit integer (2,147,483,647).
The problem is I want to make a calculator in C#. I know a solution would be use Long Int, but what if I want to add numbers even bigger than Long Int?
So consider a solution without using Long Int.
Don't...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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....
Now, this would greatly impact the work of software developers. The idea...

Hello
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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
