I have some code that performs bitwise operations on files. I'm trying to
make the code portable on different endian systems. This is not work/school
related...just trying to learn/understand.
My computer is little endian 32-bit (intel, imagine that). My code deals
with binary data in files, and I've been treating all data as native words
(32-bit) for performance reasons. I found out that if I treat the data as
long long (64-bit) I...

Hi,
1. About all C/C++ compilers, Does stack increase from high address to low address and heap grow increase from low to high? What on earth decides their increase direction, CPU architecture, OS or compiler?
2. In GNU gcc,
{
int a = {0, 1, 2, 3, 4};
bool b;
float c;
for (int i = 0; i < 5; i++) {

Hello all,
If I have a C-like data structure such that
struct Data {
int a; //16-bit value
char; //3 ASCII characters
int b; //32-bit value
int c; //24-bit value
}

Dear All !!
I am not sure the question which I am asking is correct or wrong, but
I have heard that storing the data into the big endian helps in
gting the more transfer rate, Means we can achive good speed by
soring the data in the BIG ENDIAN while transferring, If this is
correct, then how it is possible and what is the reason behind this.
Any pointers on above will be helpful, (if My question sounds correct)

Provided a unsigned integer say (32bits b31-b0 bits) and its required
to get (b19-b10) .
One approach is have a mask and right shift it
#define BIT_MASK 0x000FFC00
uint32 variable;
variable &= BIT_MASK

I want to see if this code works the way it should on a Big-Endian
system. Also if anyone has any ideas on how determine this at
compile-time so that I use the right decoding or encoding functions, I
would greatly appreciate the help.
Thanks,

Greetings,
How does one find the format of a binary file to be in Little Endian or
big Endian before we start reading the file.
Thanks

Is it possible to know whether a system is little endian or big endian
by writing a C program? If so, can anyone please give me the idea to

Thanks a ton.

Data stored on a storage device is byte swapped. The data is big
endian and my PC is little. At issue: There's a composite type ( a
header ) at the front of the files that I'm trying to read in. I'm
trying to _simulate_ the endian conversion in code below but I'm just
wondering if there's an ideal way to do this besides what's shown?
Padding produces some interesting results. Notice how the parameter d
is different in the print outs...

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...

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...
