Hi list,
I am trying to dynamically grow a 2 dimensional array (Atom ***Screen) of
pointers to a struct Atom (i.e. the head of a linked list). I am not
sure if this is the right way to do it:
/* Allocate 1st dimension */
if((Screen = (Atom ***) malloc(sizeof(Atom **) * Width)) == NULL)
perrexit("malloc");

Apologies if this is a noob question, but I've been struggling with this for quite a while...
I'm trying to convert a byte array (encrypted authorization code) into a *screen-printable* string that is displayed in a text box. Once displayed, the text will be copied, transmitted and then pasted (all manually by humans) into a second utility where the string must then be reverse-engineered into the *original* byte array. The byte array will...

I'm trying to put pointer to flexible array of structures in other
structure. I want to have pointer to array of pixels in screen
structure. Here is mine code, but I think it isn't quite all right:
struct pixel
{
int x;
int y;
int color;
};

I need (okay, I want) to make a dynamic array of my class 'Directory',
within my class Directory (Can you already smell disaster?)
Each Directory can have subdirectories so I thought to put these in an
array. The application compiles but aborts without giving me any useful
information.
What I suspect is happening is infinite recursion. Each Directory
object creates an array of Subdirectories each of which has an array of...

/**
A palindrome is a number that is the same whether it is read from
left-to-right or right-to-left. For example, 121 and 34543 are both
palindromes. It turns out that nearly every integer can be transformed
into a palindrome by reversing its digits and adding it to the original
number. If that does not create a palindrome, add the reverse of the new
number to itself. A palindrome is created by repeating the process of
reversing the...

I have 2 questions:
1- Why isn't possible to declare a static char array
inside function ?
the compiler gives this error: storage size of ‘array’ isn’t
constant.
2- Why isn't possible to output the whole array with 2 dimensions from
function?
my function looks like this:

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.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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...

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.
