smth wrong

[Limitless98]

I am using DEV-C++ on my windows PC;
When i try to run this simple program, it says
([Error] iostream: No such file or directory
compilation terminated)

i dont know what does it mean? anyone please tell me?


// writing on a text file
#include <iostream>
#include <fstream>
using namespace std;

int main () {
ofstream myfile ("example.txt");
if (myfile.is_open())
{
myfile << "This is a line.\n";
myfile << "This is another line.\n";
myfile.close();
}
else cout << "Unable to open file";
return 0;
}

Try it this way..

ofstream myfile;
myfile.open ("example.txt");

I'm sorry, I'm really new to this, still trying to read up on data files and input/output on files;

do you mean like this?

// writing on a text file
#include <iostream>
#include <fstream>
using namespace std;

int main ()
{
  ofstream myfile;
  myfile.open ("example.txt");
  if (myfile.is_open())
  {
    myfile << "This is a line.\n";
    myfile << "This is another line.\n";
    myfile.close();
  }
  else cout << "Unable to open file";
  return 0;
}

it still shows the same error message

You must a problem elsewhere, and not with the program, as I copied it, compiled it and ran the code in MS Visual Studio, with no problems. Maybe you have to put a '.h' after fstream, [ example <fstream.h> ] especially if it's an older version of Dev-C++. Anyway, try that and see if it helps. Get back to me if it doesn't, and I'll try putting it in my Dev-C++

i tried putting '.h' after fstream like you said, it's still showing error.
maybe its because of my software. which one do you use? maybe I'll try that.

This looks like something is wrong with the configuration or installation of DevC++.

I'd suggest re-installing the Orwell version of Dev C++.

A direct link to the download of IDE including the compiler is
http://sourceforge.net/projects/orwelldevcpp/files/Setup%20Releases/Dev-Cpp%205.11%20TDM-GCC%204.9.2%20Setup.exe/download

(this is getting a little dated now, but is still adequate for learning the basics).

Yeah!
i figured out the problem, nothing wrong with the program. it was me, i saved the codes as a 'C source file', tried saving it as 'C++ source file' that was no problem.
Another thing is, i just started working with data files. Currently trying to do something that involves data files. As in, creating a text file; writing in the text file; reading from it; editing it;I would really appreciate if anyone could give me something that i can read up on that can help me with this.
Thanks a lot.

Currently trying to do something that involves data files. As in, creating a text file; writing in the text file; reading from it; editing it;

The basics are covered in the tutorial:

As for editing a file, my advice is to read the entire file into the program variables. Depending on how large/complex it is, you may use an array or better still a vector. Make the changes to the in-memory version. Then write it back to the same file when you're finished.
