La parola inline è quindi una richiesta, non un comando, e il compilatore può decidere di ignorarla (e.g. flag di compilazione che ne rendono nullo l'effetto, ot… text/html 2010-05-04T03:04:46-07:00 Massimo Manghi open http://www.cppreference.com/wiki/it/io/open?rev=1272967486&do=diff open Sintassi: #include <fstream> void fstream::open(const char *filename, openmode mode = default_mode); La funzione open() viene usata con stream associati a file. Apre il file filename e lo associa allo stream corrente. Il parametro mode ha come default ios::in per gli ifstream, ios::out per gli ofstream e ios::in|ios::out per gli fstream. Se open fallisce allora lo stream viene messo in uno stato che può essere verificato tramite l'overload dell'operatore booleano '!'. text/html 2010-05-04T02:47:26-07:00 Massimo Manghi I/O Constructors http://www.cppreference.com/wiki/io/constructors?rev=1272966446&do=diff I/O Constructors Syntax: #include <fstream> fstream( const char *filename, ios_base::openmode mode ); ifstream( const char *filename, ios_base::openmode mode ); ofstream( const char *filename, ios_base::openmode mode ); The fstream, ifstream, and ofstream objects are used to do file I/O.

For example, one might use an iterator to step through the elements of a vector. The following code creates and uses an iterator with a vector:
