Hi,
 
When I read a post on-line about self-assignment, I do not understand one
line:
 
delete[] data;
 
 
My question here is not directly related to self-assignment, but about the
function of *data and n in the class array. What use are *data and n?
 
Whether they are meant to an array length n, beginning address is by a
pointer data?
 
Please help me on the function:
 
array &array::operator =(const array &rhs)
 
 
 
Thanks,
 
 
..................................
class array {
...
int *data;
size_t n;
};
 
 
In order to "fix" it one can either add an explicit self-assignment check
 
array &array::operator =(const array &rhs)
{
if (&rhs != this)
{
delete[] data;
 
n = rhs.n;
data = new int[n];
std::copy_n(rhs.data, n, data);
}
 
return *this;
}

So the first problem with the following code is that it won't compile.
 
#include <iostream>
#include <string>
#include <vector>
 
using namespace std;
 
template <typename C>
vector<typename C> create_container(int size){
return vector<typename C> myVector(size);
}
 
int main()
{
cout << "Hello World" << endl;
cout<<"The size is: "<<(create_container<string>(3)).size()<<endl;

return 0;
}

Hi,
 
When I read the for loop below, I feel that it is so different from the
normal integer as the index in a for loop.
 
It is easy to understand the first two value, i.e.
 
iter = items.begin();
iter != items.end();
 
 
My question is about the third, iter = items.upper_bound(*iter).
 
In a general for loop, the third is the step size for the variable.
Here, I do not see
 
items.upper_bound(*iter)
 
is a step from the std::multiset documentation.
 
My question can also be rephrased as what is the difference between
 
items.end()
 
and
 
items.upper_bound(*iter)
 
 
 
Can you help me?
 
Thanks
 
 
 
..................
class Basket {
std::multiset<Sales_item> items;
 
 
 
}
 
....
 
double Basket::total() const
{
double sum = 0.0; // holds the running total
 
 
for (const_iter iter = items.begin();
iter != items.end();
iter = items.upper_bound(*iter))
{
// we know there's at least one element with this key in the Basket
print_total(cout, *(iter->h), items.count(*iter));
// virtual call to net_price applies appropriate discounts, if any
sum += (*iter)->net_price(items.count(*iter));
}

Because it is not an integer.

Well, it is. Reread the upper_bound documentation.
 
And note you left out the assignment part from that step, without that it
would not update the loop variable (iter) indeed. The full step is:
 
iter = items.upper_bound(*iter);
 
 
> items.end()
 
> and
 
> items.upper_bound(*iter)
 
If they were the same, then upper_bound would not need to take an
argument, for example.

Pretty much and example of my problem now.
1) Getting data from a database that represents money
2) Comes into C++ as a string
3) Convert it double to do calculations
4) Convert it back to a string
5) Put it in the database again
 
So, $2.13 an hour turns into 2.129999999999999....I have a feeling noone
wants that printed on their paycheck.
 
I don't want to just round, because I'll have other cases where rounding
might not be the best choice.
 
What is a widely used C++ library for this kind of thing?
I see boost::multiprecision, but I'm not really clear on the licenses
bit of the documentation there.

Ah... You were talking of a very specific case of imprecision and that
just happens to be the OP's problem. That's lucky. Of course, some say
that it's better to be lucky than good. I imagine, however, that such a
library might not work very well with pounds/shillings/pence since the
relationship is not based on powers of 10 (not talking about the modern
system).

Generally speaking, the rounding of the output can take care of that as
well, even on C++ side...

In the old days, we'd just use integers and scale them as
necessary.
 
e.g. denominate in mills and divide by 1000 to get dollars.

Do you actually need doubles for the calculations or would
doing the calculations on cents instead of Dollars or Euros
also do? In the latter case simply don't use floating point
values but multiply everything you get from the data base by
100 and stuff it after proper rounding (to avoid 212.9999999
become 212 via a simple assignment instead of 213) into some
integer type. Unless this is about huge amounts of money (more
than 20 Million Dollar/Euro) a long integer will do quire
nicely. Or go for a int64 if you've got to deal with the
worlds combined GNPs;-)
 
> 4) Convert it back to a string
> 5) Put it in the database again
 
When you write it back into the data base divide by 100 and
the strings send to the data base should be fine (whatever
format you use, given that it allows for at least to digits
after the decimal point) should round correctly.
 
> So, $2.13 an hour turns into 2.129999999999999....I have a feeling noone
> wants that printed on their paycheck.
 
The problem with "I want a precision of two digits after the
decimal point" is rather simple: the computer works on binary
numbers. And most numbers that have just two significant
fractional digits in a decimal reprentation are infinite
fractions in binary (e.g. something seemingly simple as 0.1)
- and vice versa. This, obviously, becomes a problem when
you have only a finite amount of bits to store such a number
in. So there's no simple solution to the "I want two decimal
digits" problem.
 
> I don't want to just round, because I'll have other cases where rounding

If you can't switch to using cents, and thus integer types
and arithmetic, you have to very carefully analyze what you
actually need and write your code to do exactly what you want
it to do. So what's the exact scenario where rounding won't
do?

As fas as I can see the Boost license is rather liberal, allowing
you to do whatever you want with their code (even including it
into a closed source program and selling it). The more pressing
question is if "multiprecision" is of any use in this case, since
also a "multiprecision" value can't help a lot if your require-
ments call for an infinite amount of memory for storing just a
single number;-)

Sorry, cannot parse that. Do you wanted to ask if user-defined operator>>
is similar to a function? Yes, it is.
 
And nothing is redefined here. The type Item_base is specific to your
program, if there appears a function which takes an argument of that
type, then it is a new function and specific to your program, not a
redefinition. If it has common name with some other functions
("operator>>" here), then it is called an overload. It still is a
distinct function as parameter types are part of the function signature
in C++.
 
> But I cannot find the operator '>>' function definition in the

Then probably the program does not use this function. If a function is
never used then its definition is allowed to be absent.

> parameter
 
There is no "std >> operator". There are several operator>> overloads,
some declared by the standared headers, one declared in your program. Not
sure which one you are worried about and why.
 
> cout << "Total Sale: " << total << endl;
 
> I am still new to C++. Whether operator >> has been derived to the

One says "derived from", not "derived to". And one derives classes, not
operators. And no, Basket is not derived from anything and does not even
contain an operator>> declaration.
 
The line
 
cout << "Total Sale: " << total << endl
 
uses 3 different operator<< overloads, all defined in standard headers.
As there is no object of type Item_base appearing after any <<, your
operator<< overload is not used.

This is a really brain dead idea. People who rely on at() to check their
code is correct need shooting. Forcing people to do the same just isn't
cricket.
 
And another thing the correct type to use for indexing a std::vector<T>
is std::vector<T>::size_type not 'int'.

But the question remains, we inherit constructors from vector<T>, hence constructors with the name vector<T>::vector, BUT our class has the name Vec, and hence all of our Vec constructors should have name Vec NOT vector. Does the using vector<T>::vector; rename my vector constructors to Vec?

Constructors don't have names. Inheriting of constuctors basically
duplicates the constructors with certain arguments in the derived class
and makes sure that the corresponding base class' constructor is called
(of course you need to take care of initializing your own data members
in such case).
 
What book in C++11 are you reading that doesn't explain this?

So in my Vec class, if I write
Vec<int> myVector;
this will call:
vector<int> myVector?
 
and if I write:
Vec<string> myVector(3,"default");
this will call
vector<string> myVector(3, "default");
 
and if my Vec class has an extra member that requires initialization upon the creation of a Vec instance, then I should re-write all vector<T>::vector constructors in Vec and call these explicitly from my defined Vec<T> constructors?

There must be such a definition. If it is missing, the source code
is incomplete.
 
»<<« can also be defined without »fried« as follows:
 
class EXAMPLE
{ ...
::std::ostream & print( ::std::ostream & stream ) const
{ return stream << ...; }}
 
And then, outside of the class specifier:
 
::std::ostream& operator <<( ::std::ostream & stream, EXAMPLE const & object )
{ return object.print( stream ); }

So, I've been programming for a while, deriving some c++ classes from protobuf. All of a sudden, after a weekend, I do a make clean and then a make again, and I have conflicting references. I have no idea what could have happened, environment or otherwise that could make this issue show up, because the whole time that I've been compiling and successfully using my protobuf data schema's they've not barfed on this issue.
 
 
Essentially, in one of the protobuf data schema specs, I have a member called "plus". It now blows up with:
 
 
In file included from SerializerInterface.h:37:0,
from SomeClass.cpp:12:
Schema.pb.h:115:35: error: reference to 'plus' is ambiguous
const binop_type binop_type_MIN = plus;
 
 
.....
 
/usr/include/c++/4.8/bits/stl_function.h:140:12: note: template<class _Tp> struct std::plus
struct plus : public binary_function<_Tp, _Tp, _Tp>
 
 
I checked, and I don't have any kind of "using namespace std;" anywhere.
 
I understand what the issue is, but I don't know why it showed up, and I'm looking for a resolution where I don't have to edit my schema. I'm not supposed to edit the schema because that's the same across a lot of different files. I know that that schema can be made to work as well, because it worked before.
 
How can I edit either SomeClass.cpp or SerializerInterface.h to no longer conflict with plus? I can't prevent stl_function.h from being included-a library I have no power over includes it.

Actually, would there be a way that I could place a using statement just above my #include where the generated file has the issue in order that the compiler would be able to subsequently differentiate? I'd just like to either allow the compiler to know that by plus I mean the plus I defined, or just to rename the plus defined in that header so that it's no longer visible at all.

You don't. What about the library you're using? Not all library
vendors/designers are diligent about not putting 'using' directives in
the headers...

Not sure what exactly you're asking. Can you edit your own files? Can
you type "using namespace blah;" in it? Can you do that before the
first #include directive in that file? What is it you'd like us to tell
you? "Just do it"?
 
Seriously though, why don't you try doing what you think is needed? If
you think that you can learn more with a 'using' directive, add one and
see if you're correct.

You can always name your own plus to something else for starters...

Ciao a tutti. Mi chiamo Gianni, sono di Rimini, e vivo tra la mia citta' natale e Stoccolma, essendo mia moglie svedese. Devo dire che ho grande voglia di esprimere la mia gioia di conoscere l'assolutissimo genio Michele Nista (michelenista@gmx.com), di cui son felicissimo e arricchitissimo cliente. Un genio senza se e senza ma. Genio e eroe, in quanto sta salvandoci anche dalla dittatura maf..ascista ed assassina di Silvio Berlusconi. Con una creativita', energia, coraggio, e specialmente, risultati vincentissimi, che non trovi da nessuna altra parte, e mai. Non sbaglia mai e stra mai, ovvero, azzecca sempre, facendo fare tantissimi soldi, a tutti, in previsioni su azioni e materie prime. Ma azzecca anche, qualsiasi previsione in politica, calcio. Qualunque altra cosa. Michele Nista e' una vera e propria success machine, tutti i giorni dell'anno. Michele Nista e' un grandissimo Re Mida, uno dei piu' grandi Re Mida di tutti i tempi, in azioni, materie prime e non solo. E questo da fine anni 80, non solo da ora. O da due, tre anni. E' molto boicottato, il genio Michele Nista, da un topo di fogna, gia' condannato al carcere in Italia, Brasile, e indagato in
Inghilterra, che e' il pervertito sessuale, nazista, minacciante morte, e quindi, assassino: Paolo Barrai di Mercato Libero.
Non mi credete su che verme sia l'assassino fallito Paolo Barrai che attacca sempre, il genio in azioni e materie prime, nonche', eroe civile, Michele Nista? Allora date un'occhiata a cosa scrive chi da lui, si e' visto, di fatto, derubare milioni di euro, tutti risparmi che aveva:
Gruppo di risparmiatori truffati da bastardissimo criminale, pluri pregiudicato, avanzo di galera Paolo Barrai ( Blog Mercato "Merdato" Libero). Da incapace, delinquente, ladro, mega lava EURO mafiosi o "politicriminali", padanazista, berlusconazista, razzista, antisemita, super cocainomane, acclarato pedofilo, frequente mandante di omicidi Paolo Barrai ( Mercato Libero noto a tutto il mondo come Mer-d-ato Libero). Si, assolutamente, pure assassino Paolo Barrai ( "suicidatore" di David Rossi di Mps ma non solo). Schifoso lava cash mafioso e killer Paolo Barrai nato a Milano il 28.6.1965. E, prima di ora scappare come un vile ratto, a Lugano, in Svizzera (avendo paura di venire arrestato, in quanto indagato da Procure di Mezza Italia) e fra poco ancora più lontano: a Panama ( ove lo proteggerebbe il criminalissimo nazifascista corrottissimo ambasciatore lava EURO e $ mafiosi Giancarlo Maria Curcio

Ciao, sono Antonella di Milano, e faccio parte di un foltissimo gruppo di clienti derubati di tutto, dall'assolutamente criminale Paolo Barrai (Mercato Libero, ormai noto nel mondo intero come Mer-d-ato Libero). Costui è davvero un bastardo assassino sicario. A tutti noi, uniti ora in una associazione " Risparmiatori truffati da spietato criminale Paolo Barrai di Mercato Libero (e siamo gia' in centoventi, dico centiventi: di tutta Italia, Brasile, Germania e Svizzera)" ci fece andare corti ( al ribasso) sul mercato azionario italiano a inizio 2009 (col Dow Jones ai minimi degli ultimi decenni: 6900; cosa che avrebbe potuto fare solo l'Ugo Fantozzi misto a Renato Vallanzasca della Finanza: Paolo Barrai). Abbiam perso quasi tutti tra il 70 e il 100 per cento dei nostri investimenti. E quando gli telefonavamo per chiedere semplicemente che fare, mentre il mercato saliva rapidissimamente, dal Marzo 2009 in avanti, egli, se non meglio dire, "esso", come un vile ratto, scappava. Si faceva sempre negare al telefono. Mandavamo e mails, nessuna risposta. Citofanavamo agli uffici di ultra truffatrice, ultra malavitosa, ultra ladrona Bsi Italia Srl di Via Socrate 26 a Milano di suo padre, notoriamente pure pedofilo, oltre che mega ricicla soldi criminal-istituzionali o mafiosi, Vincenzo Barrai di Via Padova 282 a Milano, ci vedeva dalla telecamera e nemmeno ci rispondeva. Nemmeno ci apriva il cancello di entrata. Io non sto offendendo, sto solo dicendo la mera verità . E fra poco la faremo sapere a
