student and have been doing & studying C programming for the last 4
years).....and also a regular reader of "comp.lang.c"
I don't have a copy of ANSI C89 standard,therefore i had to post this
question:
What is the difference between "unspecified" behaviour & "undefined"
behaviour of some C Code ??

Hi
I'm wondering of what type a structure is. Of course, it is a
_structure_, but an array isn't an _array_ either. So of what type is
a structure? I'd say a pointer, am I right?

I am working on an embedded platform which has a block of battery-backed
RAM. I need to store various types of data in this block of memory -
for example, bitmapped data for control registers, strings for logging,
and structures for data points.
I want to use one function to read data from this block and one function
to write data, for example:
sram_read(OBJECT_IDENTIFIER) would return a pointer to the appriate

Can any one tell about the basics of memory padding and how memory padding will happen in case of a "if-else" statement and "switch" statement

I'm taking an intro course on C++, and our teacher is not being
clear on how stuct memory padding is determined.
If the memory used by all components defined inside a struct
falls between a certain gradient, a struct "rounds up" to the
nearest multiple of the gradient.
This teacher is somewhat erratic and has said on subsequent days
that first the padding is rounded up to nearest multiple of 4,
and then the nearest power of 2.

Hello everyone,
I heard when define a struct, it is important to make the size of the struct
memory aligned.
For example,

Assuming 16 bit or 32-bit alignment, can I assume that

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...
