title: add input values from arg in c into array for Sudoku solver
body: <p>I'm new to C and programming as a whole. I've got the basics down for a program I'm trying to get a better grasp of C, but I'm having trouble taking input from the users args at the command line to populate my array:</p>
  
  <pre><code>./sudoku.c "9...7...." "2...9..53" etc etc
  </code></pre>
  
  <p>I've tested my program using an array that I filled in and it works but that is no good if I can't take user input. My input looks something like this:</p>
  
  <pre><code>grid[9][9] = {{9, 0, 0, 0, 7, 0, 0, 0, 0},
                {2, 0, 0, 0, 9, 0, 0, 5, 3}};
  </code></pre>
  
  <p>Any suggestions?</p>
  
  <p>Any help would be greatly appreciated</p>
