Ok you are right saying that

Richard MacCutchan wrote:
That method is modifying both variables nome_cifrato and cognome_cifrato inline, and you then call setNome and setCognome. But you have already modified the names so you do not need to call the setter methods.


I didn't see it, I get confused writing the code, probably I inteded to use local variables to build cifrated name and surname.

But problem was in this function within the main

C++
void cod (anagrafica arr,string n, string c,int chiave)
{

arr.codifica(n,c,chiave); 

}


that i re-arranged this way

C++
void cod (anagrafica &arr,string n, string c,int chiave)
{

arr.codifica(n,c,chiave); 

}


passing the address to "cod". And about this, I understood the reason (Greg Utas was right about the rules but didn't apply to the real problem because i did not need to change the strings passed to the methods but the instance of the class itself). But now there is another behaviour that confuses me :

In a previous version the following method :

C++
void anagrafica::stampa()
{
 cout<<" nome  cifrato "<<nome_cifrato;
 cout<<" cognome  cifrato "<<cognome_cifrato<<endl;
}


I had to modify in this new version :

C++
void anagrafica::stampa()
{
    string nom = nome_cifrato;
    string cog = cognome_cifrato;
 cout<<" nome  cifrato "<<nom;
 cout<<" cognome  cifrato "<<cog<<endl;
}


because in the first version it was just printing nothing. Now it prints correctly. I just tried without a real knowledge behind, only some kind of sensation but I don't understand why it didn't work before and why it works now.

Anyway thanks for all the efforts/suggestions. I am just starting with c++ in order to help my children in their school exercise.
