Digest for comp.lang.c++@googlegroups.com - 7 updates in 3 topics

Mark <ma740988@gmail.com>: Jul 31 10:26AM -0700

Consider:
 
# include <iostream>
# include <cstring >
 
template < size_t Rows, size_t Cols, typename ElemType = double >
class TestMatrix
{
public :
ElemType elems[Rows ] [ Cols ];
 
//ElemType elems[Rows * Cols ];
};
 
class Foo
{
static const TestMatrix < 2, 2 > test ;
static const unsigned int val[2][2]; // Specify all dimensions.
public :
Foo () ;
};
 
 
Foo::Foo()
{
 
}
 
// works C style for multi-dimensional
const unsigned int Foo::val[][2] = { { 0, 1 } , { 2, 3 } };
 
const TestMatrix < 2, 2 > Foo::test =
{ { 0.1, 1.1 } , { 2.2, 3.2 } };
 
 
int main()
{
 
}
 
The compiler I'm using has no C++11 support, that said, how can I initialize the static const test member within Foo? Unclear why the initialization of test fails when the TestMatrix effectively mimics the c-style approach to a multi-dimensional array
 
Thanks in advance

If all you have is C++03 support, then provide a constructor that takes
an N by M array

I don't argue or debate with people. I teach them. I teach the truth
about sin, their nature, eternity and eternal life, and their need for
a savior (Jesus Christ) to pay the price of their sin for them, so that
they are set free from the punishment of sin.

There is a God. Jesus Christ is God in the flesh. Why flesh when we can't
see God? Because He came here to save us. He came to here to give us a way
out of the punishment required by God for sin.
 
Jesus told us the world would hate us. He told us that they would kill us
even. It's no surprise that many are offended by the gospel message because
many people are not going to be saved (because they will not be saved).

Ok, then be prepared to meet His endless forgiveness for being such an
arse of a person.

You misunderstood John 15. May be you did not even read it. Lot of idiots
like you are too impatient to read the Book. They think it is like license
agreement, scroll to end and press yes and you are forgiven and in heaven.
 
Jesus told in John 15 that people will hate you because they hate Him and
His Father. That may well be. However on current case you make people to
hate you because of being annoying self-centered asshole. That has nothing
to do with Jesus. That wasn't what Jesus suggested you to be at first place.

No, you annoy people. We try to forgive you that sin because we understand

The biggest problem with Christianity is morons who give it a bad name
by constantly bringing it up in venues where discussion of religion is
not appropriate.

There are no inappropriate venues, J. Clarke. Everyone who has rejected the
truth will come to this knowledge as the first thing they're aware of
happening immediately after death, because they will go to sleep, and then
be summoned by name to appear before God and give an account of their life.
 
At that point, everyone will know the truth. People will see God, see
Heaven, see eternity, and they will want it because it really is glorious.
But, because they were not forgiven by Jesus Christ, their sin debt remains,
and their name was not written down in the Lamb's Book of Life. As such,
they will be cast headlong into the burning lake of fire:
 
http://biblehub.com/kjv/revelation/20-15.htm
"And whosoever was not found written in the book of life was cast into
the lake of fire."
 
J. Clarke, Christians speak these things to people to warn them. When a
person is not actively seeking after truth, God, the Bible, a personal
relationship with Jesus Christ, there is another spirit here on this Earth
who is more than willing to step in and guide you falsely. As such, that
spirit asserts itself in your life and you begin to take on that spirit's
thinking, beliefs, etc. But that spirit is the spirit of the anti-Christ,
and it is an enemy of God, and of you.
 
It becomes so pervasive that when someone like me speaks about the things
of the Bible, they are immediately ridiculed and cast negatively in people's
thinking. The person who does not seek after Jesus Christ sees no need or
value in doing so, because that enemy spirit has been teaching them alternate
ways which do not require those things. However, that non-requirement is
only focused here on the flesh, and not on the eternal needs of our soul and
our eternal life.
 
To be clear, it's an attack against you by that enemy who uses the limited
form of our fallen-in-sin nature here upon this Earth (our flesh only) to
leverage our reason, our thinking, our feelings against the things of God.
That enemy does this because he's an enemy.
 
What Jesus Christ did coming to this Earth was to undo the work of the enemy,
and to make it possible for us to, once again, know God, and walk with God,
even here in this fallen world.
 
I come forward, and other Christians come forward, to teach you these things,
so that you won't be deceived, so that you'll have the opportunity to hear
and know the truth.
 
If your pursue the truth, it won't be me or any other Christian who teaches
you these things, but God Himself will assert knowledge of them within your
very soul. You will hear things from me and others, and you, on your own,
by His gift to you in your inmost man, will know the truth of what I say.
 
But for those who are not seeking the truth, they will never come to know
this information as it will be forever hidden from them, only because they
would not seek or hear the truth, but were content to believe the lie, so
God gave them what they were in pursuit of after many attempts to reach
them.
 
Do not be so quick to dismiss what I'm teaching you, J. Clarke. You owe it
to yourself, your family, your friends, co-workers, neighbors, to seek out
the truth for yourself, and to prove it to yourself one way or the other.
 
My words point you to Jesus Christ and the Bible. There you will find truth
in all its Earthly glory for us to come to a saving knowledge of Jesus
Christ, and the recognition that we are here upon this Earth for but a tick
of the clock, and then eternity begins.
 
Our goals are far better suited considering eternity first, then the needs
of the things of this world second, because the things of eternity endure,
and the things of this world are temporal, which means the purpose of our
goals here upon this Earth are to come to a saving knowledge of Jesus Christ,
so that we can be part of that eternity in a state reconciled rightly with
God, rather than being still in enmity with Him.
 
It's the best offering Jesus Christ has to give you, and the best offering
I have to give you: pointing you to Him for salvation, and eternal life.
And it's free for the taking ... all you have to do is come to Him and ask
Him to forgive you, and He will:

Most people know that they are about as good as others so they listen
to opinions of others. They see that they are weak, ignorant and
fallible.
 
However there are also morons who do think they are better than others,
always knowledgeable, always correct and may do what they want to and
do not need to listen to others. They think that others must listen to
them. There are no inappropriate venues for those rude morons.
 
Other people consider them repulsive, Rick. If there is God then He
will not thank you for that imago.

There is a God. He has commanded us to go forth and teach and make
disciples. This is not an "I'll be over here with a sign. If any of
you, on your own, decide that you too want to follow Jesus, then I'll
be here waiting for you" type of endeavor.
 
Christianity is active. We teach people the truth. We warn them of
sin and the consequences of sin. We do this so they too can come to
know the truth, repent of their sin, ask forgiveness, and be saved.
 
That is all.

People are willing to do /very/ dull jobs for 40 hours a week for good
salaries, a safe position, and a comfortable pension. In fact, those
are the sorts of compensations you need to provide in order to get
someone to do a job that requires skill, intelligence, education, and
responsibility - but is incredibly dull.
 
I have never had the "pleasure" of programming in COBOL, so I can't
judge if it really is dull or not. But your description here of COBOL
programmers does nothing to dispel the common view of COBOL's dullness.

You seem to be an expert in /very/ dull jobs - despite your lack of
experience in COBOL.
 
Yes, the common view of those who don't know COBOL is that it's dull.
Those who have programmed in it know better. It's no more or less dull
than C or any other programming language.

Because professionals work in the language that does what is needed, not
the language that is "exciting". COBOL may be "dull" but it runs
immense businesses.

The problem here is their sampling is flawed. For instance, they don't
look at large enterprises which typically have a low turnover rate and
when they are looking for programmers, use headhunters.
 
As a good example, approximately 5 billion lines of COBOL are written
each year (https://cis.hfcc.edu/faq/cobol). But the list doesn't even
show COBOL.
 
Looking at the number of jobs, etc. is a good way to check for job
openings - but due to the difference in turnover rates (i.e. C
programmers have a much higher turnover rate than COBOL programmers) is
not a good measurement.

How to explain the lower turnover rate for such
a dull language like COBOL? I'm not sure which
is worse Java or COBOL.

Who are you to judge?
 
Why does one language need to be "better" than any other? Use
what solves the problem most effectively - and one can solve business
problems in COBOL much more effectively (and quickly) than one can
solve them with C or C++.

I don't trust in those rankings. If you consider TIOBE for example, C++
is in 3rd place and R is in the position 17th (not to mention that the
1st and 2nd places are swapped in both rankings)

Solid job, good salary, great benefits, excellent working conditions.
Most of the COBOL programmers I know have been at it for 20 years or
more with the same company. And the ones who have retired have
comfortable pensions.
 
And they don't think it's dull at all. But who are they do judge - they
only do it 40 hours a week.

I wouldn't consider 5 billion lines of new code every year to be "legacy".
 
I also forgot to mention - the figures I remember from IBM stats was 2
billion each year. While looking for the reference, I came across this
one, which looks to be more accurate (IBM made their estimates based on
surveys of their customer base - large, but hardly all-encompassing).

Which is another reason why it's so popular.

/exactly/ is your use case)?

Hmm, why is it not possible to inspect the internals of a library? Too
much detail?
 
Maybe this site is helpful to you: https://swtch.com/~rsc/regexp/
The details of the transformation are explained in the first link
https://swtch.com/~rsc/regexp/regexp1.html
and an implementation is linked from the main page. I haven't studied it
in detail, but it looks close to what you are looking for.

My usecase are regular path queries (RPQ) on directed, labeled graphs.
Basically you want to check if a vertex pair is connected by a path
whose label (concatenation of the edge labels) satisfies a regular
expression. The alphabet for the regular expression is the set of edge
labels.
 
Yeah, that's a very special usecase. So, i think, i need direct access
to the automaton as i have to take transitions more directly (during
traversing the graph). I don't think one can use std::regex for that.
Is it even possible to define an aplhabet for std::regex?
 
Regards,
Frank

It is probably possible to rip the specific parts out of the library. I
was just wondering if there was something more readily available.

I found this site too and i plan to use it as a reference for my own
implementation. Thanks for pointing out that there's also an
implementation available on the site. I missed that before.

I was under that impression too, but based on cppreference, which is
perhaps not the best source. Does anyone know for sure?
 
Anyway, it's been reported to me that with
 
Xcode, Apple LLVM 7.1 with -std=c++14 and libc++
(LLVM C++ standard library with C++11 support)
 
it seems not to be the case.

You are correct clang version 3.8.0 with libc++:
http://coliru.stacked-crooked.com/a/d4dfc706d72fc3bd
 
The libc++ architect Howard Hinnant explains why is that in answer to
same question:
http://stackoverflow.com/questions/31974237/why-is-libcs-vectorboolconst-reference-not-bool
 
I myself think that 'std::vector<bool>' was mistake.
I prefer 'std::bitset' instead of 'std::array<bool, N>' and
'boost::dynamic_bitset' instead of 'std::vector<bool>'.

I want to have a class template that has a specialization for bool, and also for std::vector<bool>::const_reference if that type differs from bool.
 
I came up with this:
 
template<class T, class Enable = void>
class A
{
public:
A()
{
std::cout << "default" << std::endl;
}
};
 
 
template <class T>
class A<T,typename std::enable_if<std::is_same<T,bool>::value>::type>
{
public:
A()
{
std::cout << "bool" << std::endl;
}
 
};
 
template<class T>
class A<T,typename std::enable_if<std::is_same<T,
std::conditional<!std::is_same<bool,std::vector<bool>::const_reference>::value,
std::vector<bool>::const_reference,
void>::type>::value>::type>
{
public:
A()
{
std::cout << "std::vector<bool>::const_reference" << std::endl;
}
};
 
// With VS, the types are the same
A<std::vector<bool>::const_reference> a1; // With VS, prints bool
A<bool> a2; // With VS, prints bool
 
Is there a simpler way?
 
Thanks,
Daniel

That is odd ... AFAIK it is *required* to be bool.

Wasn't it simple enough?
May be if you write that, then it is simpler to follow logically:
 
template<class T>
class A< T, typename std::enable_if<
std::is_same< std::vector<bool>::const_reference, T>::value
&& !std::is_same<bool, T>::value >::type >

What it is? How to comment it? What went from where to where?
There that statistics programming language "R" is at #5 and

Isn't it hardware platform? :D It feels like some sort of bad joke.

Which is why it's a good idea to use a header guard related to the file
name. But you missed that part - because you don't read so well.

Two things.
 
First of all, that's not the header guard I said.
 
Second of all, I don't have MSVC 2103 (does anyone? That's not for
another 87 years), but your code compiles just fine with gcc 5.4.0.
Either the code you presented is not what you compiled (maybe you have
another PeopleConcert.h?), or you have a problem with your compiler.

Whoosh! That's the sound Paavo's example makes as it passes completely
over your head.
 
Since this seems too subtle for you to follow, I'll explain it in small
steps.
 
The standards (C and C++) make certain classes of identifiers
"reserved". This includes identifiers that start with two underscores,
and identifiers that start with one underscore then a capital letter.
Some of these are reserved for future language changes, others are
reserved for the implementation.
 
It is good programming practice to take this into account when choosing
your own identifiers.
 
"Why?", I hear you ask (since you clearly don't understand at the
moment). Avoiding reserved identifiers in your own code means your
identifiers won't crash with reserved identifiers in a different or
future compiler. Similarly, implementations avoid non-reserved
identifiers to avoid crashes with the user code.
 
So you don't avoid using an identifier like "_PPLCONCRT_H" just because
it might cause trouble /now/, you avoid using it because it might cause
trouble in the future. A future C compiler - such as MSVC 2103 - might
use that as an include guard in one of its own implementation-supplied
header files.
 
Do you see the point now?

Whoosh. You completely missed my response.
 
No, I didn't miss Paavo's comment. I just pointed out he has a problem
in either his code or his compiler, and that he didn't use the example I
did. Nothing more, nothing less.
 
But you're too dense to understand that.

Hello,
 
does anybody know of any library transforming a regular expression as
a string to an equivalent automaton (minimized DFA preferable)? I don't
want to do string matching directly, so most of the regex library
can't really help me. I want access to the automaton. Does anybody know
of a library or framework providing this?

Frank

Some of my students have used
http://hackingoff.com/compilers/regular-expression-to-nfa-dfa
I don't know if its available for download.
 
But then, it is not a bad exercise to do it yourself... Especially if
you have special requirements on characters, etc.
 
(This has little to no relation to C++, you may get more help from
comp.theory or comp.compilers I guess.)

Yeah, i probably have to do that. For my current project it would just
be a nice-to-have, a simple string interface. Let's see if i find the
time for that. A nice description:

Hi,
 
the following code should compile according to the standard (library).
 
#include <iostream>
using std::ios;
#include <fstream>
 
 
 
int main() {
int offset = 0;
ios::seek_dir org;
org= ios::beg;
std::ifstream input("Test.txt");
input.seekg(offset, org);
return 0;
}
 
 
g++ (5.4.0) gives the following error messages:
 
IOS_Test.C: In function 'int main()':
IOS_Test.C:12:26: error: invalid conversion from 'std::ios_base::seek_dir {aka int}' to

Yes it is your bug and compiler complains cleanly. All you need is to
read a bit of docks. I can highlight the points: That 'ios_base::beg'
is of type 'ios_base::seekdir'. That 'ios_base::seek_dir' that you use
is deprecated member type and compatibility with 'ios_base::seekdir'
is nowhere required. See yourself:

Many thanks!
I didn't realize that there are two different type(def)s:
seekdir and seek_dir.
