[Dev-C++] Re: illegal operation in while loop

I figured it out --- I did not allocate space for "buffer."        Alan

Subject: illegal operation in while loop


All of a sudden, I started getting an "illegal operation" in a while loop.
I cut everything out of the loop, but I still get the error.  The pertinent
code is shown below.  Any ideas?  I have used the same input file from the
start.

            If I change "input_file.getline(buffer, 200, '\t')" to
"input_file.get(c)" then the program does not encounter an error.


Thanks, Alan

 char *buffer = "";
 char c;

 ifstream input_file ("test_tab_win.txt");

 while (input_file.getline(buffer, 200, '\t'))
       {
          // nothing here
       }
