I still sometimes write C-like casts like
 
if (MyPointer == (classPincoPallo *)(0)) {}
 
then QT ide slams me for "old styled" fashion, so I rewrite
 
if (MyPointer == static_cast <classPincoPallo *> (0)) {}
 
and it again complaints until i correct further to
 
if (MyPointer == static_cast <classPincoPallo *> (nullptr)) {}
 
now, WHAT exactly is the nullptr ? Is it really different
from ZERO (all-zeroes-bit pattern of the word size) ?
 
If it is a zero, why the ide complaints as it was just
casted in a zero of a proper type ?
 
if it is not zero, is it some "system-dependent" numeric
constant ?
Why should it better than zero ?
Is it a bigger than bigger ram address value ?
 
I'm confused about the pointer "nullity" management.
 
Long ago casting a 0 had been enough :\

The nullptr is just a literal for a null pointer, of any pointer type.
Absolutely no reason to cast it to anything - it already is of that
pointer type (and all others as well).
 
Also, to be predantic, the null pointer doesn't have to be all-zero-bits
if the system prefers some other representation (all 1-bits have been
seen on systems without an MMU, where actually writing to address 0
could break the OS :-).
 
In any case, both 0 and nullptr will represent the proper value,
whatever it is.

It's just the IDE bullying you.
 
`nullptr` is more safe than `0`, because the latter can be interpreted
as integer zero. However, `0` can be more readable.
 
It's not a choice that the IDE can reasonably make, so check if you can
configure it away?
 
The `nullptr` notation originated with Scott Meyers, who defined a
nullptr_t class in the C++03 days. And so, following that design,
`nullptr` in itself designates a value, of type `nullptr_t`, that is
/convertible/ to any T* nullpointer. One nice feature of that scheme is
that one can use `nullptr_t` as a function parameter type.
 
A nullpointer of a given type T* is a nullpointer regardless of
notation, and it's not guaranteed to be the bitpattern all zeroes even
when it's designated by `0`.

This should read:
 
if (!MyPointer) { /*...*/ }
 
or if you insist:
 
if (MyPointer == nullptr) { /*...*/ }
 
There is no point in adding extra noise to your code.

You clearly over-engineered there.
 
Installed also qt-creator to see what Clang-Tidy and Clazy in it say
by default and how to change it.
 
By default it seems that:
 
if (MyPointer == 0) // gives warning: zero as null pointer constant

if (!MyPointer) // no warnings
 
if (MyPointer == nullptr) // no warnings
 
I actually like last two better so I would not touch it but lets see if it
is possible to change so all 3 to give no warnings.
 
Seems that disabling the warning .pro file like ...
 
QMAKE_CXXFLAGS += "-Wno-zero-as-null-pointer-constant"
 
... removes it also in editor.

why not just auto? What's the point of both auto and return type?

It may be that you're asking about the syntax.
 
Well, `auto f() -> T` for /trailing return type/ was introduced in C++11.
 
Now that you have a name you can look it up.
 
`auto` for /deduced return type/, like `auto f() { return 3; }` was
introduced in C++14, almost like sabotage of the C++11 syntax.
 
Apparently support for `auto auto`, writing `auto f() -> auto { return
3; }` in order to specify deduced return type explicitly, was introduced
in C++17. But of this I'm less sure. Even though compilers I've tried
accept the syntax I don't even know, 100%, that it's valid C++.
 
---
 
It may alternatively be that you're asking why most C++ programmers
still generally specify return types instead of using deduced return type.
 
A deduced return type can be very convenient for e.g. a `begin()` member
function that just defers the work to some member container's `begin()`.
 
But a deduced return type can in the worst case mean that you have to
delve to the bottom of an arbitrary long call chain in order to find out
what the return type, that the compiler knows, is. On the way you may
have to do overload resolution and template instantiation just like the
compiler, to figure out where these calls go. You may have to use a
debugger.
 
That's just a waste of time for the programmer.
 
And so it's strongly counter-productive to use this feature in general.
 
---
 
If you meant the second interpretation, then I think a better question
is whether there are programmers who regularly use deduced return type,
and if so, what on Earth makes them do that counter-productive thing?
 
In my opinion, if they exist, then they're likely a collection of total
incompetents, the genuinely insane and maybe herd followers, just as
with any group that does irrational things: some are insane, some don't
understand any of it, and some (in religion that's most) follow the herd
in order to derive social advantages, or avoid social disadvantage.
 
But I would guess that any group of C++ programmers using deduced return
type is not yet large enough that there would be any herd followers.

Just one question. What's the point of auto then?

It's still unclear what you're asking about. You quoted everything to be
sure not to give any indication. I snipped all that.
 
If you're asking about the syntax, then in C++11 the point was that
`auto` was an available keyword to use in the new syntax. The original
meaning in C, of automatic storage, was covered by that being the
default. For the new syntax, trailing return type, it was not mnemonic,
but it was deemed better than the other available keyword, `register`.
 
register foo() -> int
 
Nah.
 
But the committee could have chosen to use operator notation, like the
lambda notation:
 
[] foo() -> int
 
Then they'd have had a nice notation where the difference between a
named function and a basic unnamed one (lambda), would simply be that no
name was provided for the unnamed one. One conceptual problem with this
scheme is that the named functions would be declarations while the
unnamed ones would be expressions. I don't offhand see that the
possibility of `[]` occurring in a possible-declaration context would be
problematic for a compiler, e.g. leading to parse ambiguities, but maybe
it would -- the committee includes folks from compiler vendors, folks
who know a lot about the inner workings. There is however a problem of
similar notation implying similar functionality. And it doesn't make
much sense to specify captures for a named function declaration.
 
Alternatively the committee could have chosen to open up for new kinds
of identifiers, such as `#foo` and `$foo`, to use as new keywords (the
problems with these is that they can introduce conflicts with existing
preprocessing, in particular #foo with the *nix convention for shell
scripts). Or they could have chosen to introduce contextual keywords,
keywords that are only keywords in certain contexts, which would reduce
or eliminate breakage of existing code. Or they could have chosen to
simply add new keywords as they've now done in C++20 (there's a host of
them). Or they could go for ugliness, like `__foo`, which is safe and
readable but just ugly. They chose neither of these approaches.
 
I.e. they were still very very conservative for C++11, going for
technical safety instead of readability where readability mattered, and
now in C++20 for more esoteric little used features they feel more free. :(

I think that all that matter is exercize in futility. We already have
function syntax, this one has sence only on unspecified return type,
for what auto keyword is handy. I will never use it in my code as it can
serve just to bring confusion...

Whether that is likely true or not, you are now feeling competent to
evaluate something that you have just shown you didn't understand
moments ago.
 
It's unlikely that you have gained a full understanding in so short a
time, and committing to an evaluation this early makes the climb towards
learning more, more difficult.
 
If instead you keep an open mind, defer the rash impulse to evaluate,
you may learn new things faster.

I undertstood it perfectly since auto keyword brought me for purpose
auto return type.
I understand that you like new syntax for functions more, but I don't
call it C++...

What short time? C++14 was released years ago...

This is not matter of open mind rather C++. That syntax is not C++
rather SomeOtherLanguage...

I appreciate your right to post the way you want here, and I fully
appreciate your motive of cheap entertainment. But there comes a point
in which such threads become more akin to Calvin and Hobbes "You're a
potty mouth! No, /you're/ a potty mouth!". Surely that can no longer

The purpose of this newsgroup is to discuss C++. I don't recall
seeing you do so here. If your personal entertainment is more
important than sticking to the topic of the newsgroup, I can get
along without seeing any of your contributions, so I'll add you to
my killfile as well.
 
I find it rude that you impose on the other readers of this
newsgroup the burden of either adjusting their filters or reading
your off-topic and frankly boring "entertainment". I encourage
you to stop, but it will no longer matter to me personally.
 
Bye.
