I have done the overload on the operator >> and << in the class Attore.
These 2 overload work correctly.
I have done the overload of the same overload in the class Film. The class
film ha inside an array of pointer to Attore.
I have written these overload in these ways. the overload of << work
correctly the overload of >> I don't know. I compile the class correctly,
when I insert a film through the operator >> I don't receive error, but when
I try to stamp the fil through the operator << I have an error during the
execution of program. Why this error? Depend from the overload of >>.
There are the overload of the operator<< and >>:
ostream & operator<<(ostr eam &out, const Film &f){
out<<f.getTitol o()<<endl;
out<<f.getAnno( )<<endl;
for(int i=0; i<f.countAttori (); i++){
out<<*(f.attori[i])<<endl; //use the overload of << in Attore, in Film I
have defined: Attore *attori[5]; this overload works correctly
}
return out;
}
istream & operator>>(istr eam &in, Film &f){
char nome[30];
int anno;
Attore a;
in>>nome;
in>>anno;
in>>a; //I use the overload of >> in Attore;
f.setTitolo(nom e);
f.setAnno(anno) ;
f.addAttore(a);
return in;
}
how can i resolve this problem?
Thanks 3 2235

problem with countAttori() perhaps?
out<<*(f.attori[i])<<endl; //use the overload of << in Attore, in Film I have defined: Attore *attori[5]; this overload works correctly } return out; }
istream & operator>>(istr eam &in, Film &f){ char nome[30]; int anno; Attore a; in>>nome;
This could overrun and will only get one word. Use a std::string.
in>>anno;
You are not checking for success at all.
in>>a; //I use the overload of >> in Attore;
You can have 5 actors but the input routine only allows 1.
f.setTitolo(nom e); f.setAnno(anno) ; f.addAttore(a);
does what to countAttori() ?
return in; }

countAttori() returns the number of Attore in the array. The max number is
5, but in the array could be less of 5.
I insert with the operator only 1 Attore.
In the overload of >> in the film I have written:
char title[30];
in>>title;
In this way I can give a title of only one word, with the use of string Can
I give a title with 2 or more word?
For insert a film I write this in the prompt:
Goffy(title) 1990(production year) Jacques(actor name) Rosseau(actor
surname) 11/11/1770(actor date of birth)
but hao can a give a title with 2 or more word?
Example:
Goffy go to disco(title) 1990(production year) Jacques(actor name)
Rosseau(actor surname) 11/11/1770(actor date of birth)
Thanks.

I gathered that but where is the current size held and are you setting it on?

Can I give a title with 2 or more word?
No - the only simple way is to allow a whole line
for the title (and possibly every string field) and use getline to read it
(preferably into a std::string).

Hello all,
After perusing the Standard, I believe it is true to say that once you
insert an element into a std::list<>, its location in memory never changes.
This makes a std::list<> ideal for storing vertices of an arbitrary n-ary
tree where a vertex contain pointers to its parent / children. These parent
/ child vertices need to stay put if we've got pointers to them somewhere!
Am I correct in my assertion?

Obviously you can't just use a simple for loop, since you may skip
over elements.
You could modify the loop counter each time an element is deleted.
But, the loop ending condition must be checked on each iteration,
since the Count changes as you delete elements. I would think it is
guaranteed to be computed each time, and not cached.
So, is this the best way?

Hello,
I have a class hierarchy distributed over 3 native C++ dlls. The base class

I need the different dlls as the sub classes implement the base class's pure
