I need a smart char * class, that acts like a char * in all cases, but
lets you do some std::string-type stuff with it. (Please don't say to
use std::string - it's not an option...). This is my attempt at it,
but it seems to be lacking... I'm aware that strdup() is nonstandard
(and a bad idea for C++ code) - please just bear with me:
/* Assume relevant headers are included */

I understand the problem I'm having but am not sure how to fix it. My
code passes two char* to a function which reads in some strings from a
file and copies the contents into the two char*s. Now when my function
returns, the values stored in the char* are some garbage values (perhaps
because I didn't allocate any memory for them).. but even if I allocate
memory in the function, on the return of this function I see garbage..
here is my...

In a post regarding toupper(), Richard Heathfield once asked me to think
about what the conversion of a char to unsigned char would mean, and whether
it was sensible to actually do so. And pete has raised a doubt in my mind
on the same issue.
Either through ignorance or incompetence, I've been unable to resolve some
issues.

Hello everyone.
I'll ask this even at risk of being accused of not researching adequately.
My question (before longer reasoning) is: How does declaring (or defining,
whatever) a variable **var make it an array of pointers?
I realize that 'char **var' is a pointer to a pointer of type char (I hope).
And I realize that with var, var is actually a memory address (or at

I get 4 of those errors. in the same spot. I'll show my parent class,
child class, and my driver.
All that is suppose to happen is the user enters data and it uses
parent/child class to display it.
here is the 4 errors.

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

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...
