hi,
after reading some articles and faq,
i want to clarify myself what's correct(conform to standard) and
what's not?
or what should be correct but it isn't simply because compilers don't
support.
(first i compiled them with g++3.x. ERR means compiler will bark,
otherwise it does accept it. Then the Comeau C/C++ 4.3.3 comes)

Can someone please explain to me the difference between these two:
function1( const int a)
function2( int const a)
Both seemed to compile, but what is the difference between the two above.
And why would one choose one over the other.
moreover, I thought there was a difference between the two below where one
would not let the value change whereas the other one would not let the

I've searched this newsgroup's archives but couldn't find any posts that
provided any "rule of thumb" recommendations for use of const in function
parameters.
I appreciate there is no need for scalar variables to have const defined,
but how far should it go with pointers?
The Standard Library has functions defined that specify const, for example,
puts(const char *s) but why not go the extra bit and make it puts(const char
* const s)?

What are the advantages of using const as often as possible in C?
Does it help to declare integer function arguments as const? How about
pointers and automatic const integers?
const int func(const int x, const float *f)
{
const int retval = x;
return retval;
}

Hello,
First off, I know this code will not compile and am not asking for
someone to solve it for me.
What I am asking is from the code below, how does one first define an
array as a constant, and second pass the values in and out of
functions?
Here is the code; Thanks in advance:

In my function/method paramater list I try to keep constant correctness.
I.E. I would use:
int Foo( const char* a, int b )
instead of
int Foo( char* a, int b )
My question reguards int b. Would it be more correct to make it
int Foo( const char* a, const int b )
instead? I do know the effect of this would be that I can't change b in the
function, which I normally never do anyway.

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...
