g++ include string.h

[Christian Rudiger]

Hi there,

i'm kind of newbee to c++ programming and try to do my first steps with 
the gcc in delivered with cygwin.

I'd like to include the string.h into my little program but it wasn't 
found as the compiler doesn't accept my string declarations.

here's my program and what the compiler sais:
*****************************************************

// reading a text file
#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>
#include <windows.h>
#include <string.h>
#include <string>

string FILE_POSTFIX = "myfile.txt";

   int main (int argc, char** argv) {
     string filename = FILE_POSTFIX;
     string output;
     ifstream in (filename) ;
     while (in){
     in >> output ;
     cout << output << endl;
       }
   }
*********************************************************
