Hello
I'm working on a piece of code which I did not write and it has
variables defined as:
unsigned short i:13;
unsigned short j:13;
unsigned short k:3;
As I understand the code, this means that i is reduced to being coded on
13 bits (same for j) and k is reduced to 3 bits.

I was compiling a program written by someone else about six years ago, and
widely distributed at the time. It also includes makefiles for many
different systems, so I know it has been compiled with many different
compilers.
I got compile errors when it used va_arg to fetch an argument of type short.
That seemed a little strange to me, so I changed it to int and it compiled
just fine.
So now I wonder, just what is the rule for va_arg...

Hi,
Are 1 through 4 defined behaviors in C?
unsigned short i;
unsigned long li; /* 32-bit wide */
1. i = 65535 + 3;
2. i = 1 - 3;
3. li = (unsigned long)0xFFFFFFFF + 3;
4. li = 1 - 3;

I wrote this:
short s1 = 0;
short s2 = 1;
short s3 = s1 + s2;
And gor this compile error message: Cannot implicitly convert type 'int' to
'short'
What is wrong here?

will occurs the following error:

explicit conversion exists (are you missing a cast?)
and this is correct:

I encountered a problem after we had converted our declarations of
'unsigned short int' to uint16_t. In one instance, whoever did the
conversion failed to delete the 'short' keyword so we had a 'uint16_t
short'. The compiler (GNU 3.3.5) allows this but ignores the original
unsigned keyword and initialzes the variable as a signed short int. I
created a very simple test program just to see what was happening:
#include <stdio.h>

Could someone please tell me what is wrong with the following -ugly-
piece of c++ code. Why when I explicititely set the template parameter
my gcc compiler start getting confused:
bla.cxx: In function 'int main()':
bla.cxx:25: error: call of overloaded 'foo(short unsigned int*&)' is
ambiguous
bla.cxx:2: note: candidates are: void foo(OutputType*)
bla.cxx:10: note: void foo(PixelType*)

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...

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...
