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.
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concerned that some of the information may be outdated...

"The only operators that cannot be overloaded
are :: (scope resolution), . (member selection), and .* (member
selection through pointer to function). Quoting from Stroustrup's 3rd
edition of _The C++ Programming Language_, section 11.2 (page 263),
these three operators 'take a name, rather than a value, as their
second operand and provide the primary means of referring to members.
Allowing them to be overloaded would lead to subtleties.'"...

Hi,
I know it is possible to refine operators (like +, -, * or /) on classes.
But is it possible on simple types ?
ex :
If I have a type like :
typedef int vector
is it possible to redefine a + operator on the vetor type ?
Thanks !

hi
i wasnt to know the answer for the following.
now ,u can overload all the operators which are basically determined at
runtime (coz' of whch operators like sizeof())cannot be overloaded.
now my doubt is , if u have something like
p->a ....where p(say) is a pointer of a user defined type, then u can
overload this because p is determined at runtime ???is this right ???
also if "a" is an object of the some user defined class,

Hi,
As you know there are few operators in C++ which cant be overloaded.
They are:
.., .*, ::, ?: , new , delete , sizeof , typeid , static_casr ,
dynamic_cast , const_cast , reinterpret_cast .
Theremust be some reason for this restriction for each of the

Greetings.
I have some questions that I would like to clear out.
1. Why do operators have to be static? (This question relates to the
language specification)
2. More importantly, couldn't there be operators that were tranlated at
compile-time to "normal" methods?

Having had a look at the C++ FAQ, comp.lang.c++ & comp.std.c++
archives and Stroustrup's FAQs (particularly the following:
<url:http://www.research.att.com/~bs/bs_faq2.html#overload-dot/>)
I am left to wondering why Stroustrup doesn't mention the
*_cast<> operators or operator .* in that particular FAQ.
Archived discussions have convinced me that .* _cannot_ be overloaded.
I have gathered a notion (perhaps incorrectly) that the *_cast<>...

Anyone with me here? (I know the deadline for P3 PEPs has passed; this
is just talk.)
Not many people are bit-fiddling these days. One of the main uses of bit
fields is flags, but that's not often done in Python because of keyword
arguments and dicts, which are lot more versatile. Another major use,
talking to hardware, is not something oft done in Python either.
It seems like this occasional usage wouldn't justify having built-in...

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,...
