I am writing a function that given nx1 vector a and a nx1 b solves a
system of equations f(a,c)=b for a nx1 c.
While writing the function:
1] Should I allocate the memory for c within the function and return
the allocated memory?
something that leads to
double *solve(const double *a,const double *b,int n)

double *c;

I tried building libpcap and tcpdump from my Red Hat 7 RPMs. The
tcpdump make couldn't find ioccom.h and sockio.h.
When a header file is missing, how do you find it?
Thanks.

Hi,
In my couple of years of experience, I have never found a single
instance where I needed to use unions and bitfields(though I have used
structures).I was just imagining where would these find
relevance.Though both of these(bitfields and unions) are used where
space is a constraint(so I can assume always in embedded systems,where
memory is particularly less)and we want to save space/memory.
As far as I have read, there is no...

Hi ,
Recently I have been commited to the task of "translating" some complex
statistical algorithms from Matlab to C++. The goal is to be three
times as fast as matlab ( the latest) .
I've used various techniques ( loop unrolling, loop jamming...) and
tried some matrix libraries : newmat (slow for large matrix) , STL
(fast but ..not usefull) , hand coding (brain consuming...), and
recently Meschach...

I'll be using gcc under Red Hat Enterprise Linux.
Where do I find information about the low-level calls to the operating
system from compiled 'C'?
For example, if I want to cause a process to sleep, or look at the
permissions of a file ... where is this written down?
Thanks, Dave.

Hi,
Can you please recommend any good books for c++ algorithm/data

Hello:
I have a bunch of related items that are either parents, children or
not directly related to each other. In my case, I have a bunch of
database tables joined with foreign keys. Another example would be a
family tree.
I would like to take a flat list of these items and build the
hierarchy. So, in other words, I would like to take one element and
figure out its relationship to the other items. When I am all done, I

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...
