cout << buffer << endl;
}
return 0;
}

I'm not a C++ coder, so can not help you here. I did try to compile your code and got warnings on my Linux system.

There is a dedicated programming section here at LQ where your thread will fit better. You can ask a moderator to move your thread there by using the report button at the bottom of your post.

steve2688 you do know this is a Linux forum and NOT an MS windows ( xp,vista,windows 7 beta) forum ???
to read a text doc

Code:

nano /path/to/the/file/FileName.txt
------- or ---------
vi /path/to/the/file/FileName.txt

if you want to read files in DOS, use the type command (or just type "edit" on the command line. The "type" command is suitable to files if you want to automate. No need to use C++ !!

@John VV and ghostdog74

I think steve2688 is trying to write a small program as an exercise.

Haven't looked at C++ for a long, long time but anyhow:

Code:

#include <iostream>
#include <fstream>
#include <cstdlib>

using namespace std;

int main ()
{
         char buffer[50];
         ifstream examplefile ("example.txt");

         if (! examplefile.is_open())
          {
           cout << "Error opening file";
            exit (1);
           }

       while (! examplefile.eof() )
       {
          cout <<"hello";
          examplefile.getline (buffer,50);
          cout << buffer << endl;
       }
 
      return 0;
}
