After fixing "fstream.h" header (there is no such header in modern C++) and fixing declaration of main() by returning int (as standard c++ requires) the code compiles just fine in Visual Studio (other compiler may require include cstdlib too).

dude that fstream.h is a fiLe handling header.....bt after including int with main && cstdlib.h header file prOgram is still showing the same error !!!!!

DUDE all x.h headers in c++ are just x so fstream.h is just fstream

If this code does not work then try a modern compiler, not crap like Turbo C++ which you are probably using.

it wouldnt actually make a diffrence its just more of a syntax thing. why the hell did you post this twice dude. just start posting on the other one and stop on this one.

try this (its what i do):
1
2
3
 
#include <string>

string file = "


damn it... i just realized what was wrong... its ios::in | ios::out
(it might be ios_base)
