title: Passing file pointer into functions, and file not being read correctly
body: <p>I think my problem with my code that the file is not being passed correctly. The input is a file with three lines
  1 2 3;
  4 5 6;
  7 8 9;
  and the output is a Segmentation fault (core dumped), the output is supposed to print the first line 1 2 3.</p>
  
  <pre><code>#include &lt;stdio.h&gt;

  int getNum();
  int getLine();
