// mărimea fisierului ce urmeaza a fi citit
unsigned long lungime;
// unde vor fi salvate in memorie datele
char *buffer;
// streamul de intrare pentru citire
ifstream file(fisier.c_str(),ios::binary);
// se merge la sfarsitu fisierului
file.seekg(0,ios::end);
// returneaza marimea fisierului
lungime = file.tellg();
// se merge la inceputul fisierului pentru citire
file.seekg(0,ios::beg);
// se aloca spatiu pentru citire
buffer = new char[lungime];
// se citeste continutul fisierului
file.read(buffer,lungime);
// se inchide streamul de citire
file.close();
// se returneaza datele citite
return string(buffer);
}
int main()
