title: Returning a 2D char array in C
body: <p>I messed around with this enough but I really don't get it.</p>
  
  <p>Here is what I want to do: Take a 2D char array as an input in a function, change the values in it and then return another 2D char array.</p>
  
  <p>That's it. Quite simple idea, but ideas do not get to work easily in C.</p>
  
  <p>Any idea to get me started in its simplest form is appreciated. Thanks.</p>
