Iso c ++ for file copying

I recently read think in C ++ and found that the C ++ standard library is actually very functional, but it was used too little in the past. The file copy here is an example. Implementing a file copy function is so simple: # Include < Fstream >
# Include < Iostream >
# Include < Cstdio >
Using   Namespace STD;

Void Copy ( Const   Char * Srcfile, Const   Char * Destfile)
{
Ifstream In (Srcfile );
Ofstream Out (Destfile );

Out   <   In . Rdbuf ();
Out . Close ();
In . Close ();
}
