There's a rather nondescript book called "Using Borland C++" by Lee
and Mark Atkinson (Que Corporation) which presents an excellent
discussion of overloaded new and delete operators. In fact there are
quite a few things that I learned that I did not know before. For
example, while I knew that the new and delete operators can be
overloaded for classes, I did not know that that the global new and
delete operators can also be overloaded. ...

I am presenting below a summary of what I have gathered. I would
appreciate if someone could point out to something that is specific to
Borland C++ and is not supported by the ANSI standard. I am also
concerned that some of the information may be outdated...

Hello all,
I'd like to find a source on the web that discusses, in a comprehensive
manner and in one place, everything about new / delete. It should include
overloading operator new, the new operator, placement, nothrow, arrays,
etc...
My books cover the topic, I've found FAQs on the web that cover the topic,
and so on, but all the sources I've found are disjointed. There's a bit on
this page, a bit on that page, and so on. The...

I use the code below to study delete and destructor.
#include <iostream>
using namespace std;
struct A {
virtual ~A() { cout << "~A()" << endl; }; //LINE1
void operator delete(void* p) {
cout << "A::operator delete" << endl;

I have an overload delete operator as below

We all know that a new-expression,
foo* a = new foo() ;
allocates memory for a single foo then calls foo::foo(). And we know
that
void* p = ::operator new(sizeof(foo)) ;
allocates a sizeof(foo)-sized buffer but does NOT call foo::foo().

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
