Has anyone got any ideas how I could go about producing a maths program for
Primary School pupils? The coding isn't such a problem (ie random numbers
etc), it's acctually figuring out how to interface it or what objects to use
where etc.
I am having two or more random numbers up to say 20 displayed on the screen
and I want the child to be able to fill in the answer (txt box obviosly).
What can I use to display and use the sum in coding?...

I picked up the following script from an old post on this newsgroup. It
works fine for numbers to two decimal places, but I have a need to format
numbers to three decimal spaces from this: 1234.394 to this: 1,234.394 (no
rounding). I don't quite follow the reg exp in the variable fmt or what the
$1 and $2 do in the myNum replace method. Any enlightenment/help would be
appreciated.
Thanks, John

Hello, I am trying to write a program to solve a simultaneous equation. It runs through all the possibilites for x, and if any of them forfil the conditions of y, then it is displayed. My problem is that i don't know how to make it so that only positive integers are displayed. What I have done was change a double value integer, and then display that, but all it does it cut of the decimals, not give me all the possibles for x and y that are whole...

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,...

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.

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...
