  <p>Every time I use <code>using namespace std</code> I always get that "thats a terrible programming habit".
  Now I'm graduating this December with my B.S. in C.S. but I don't claim to know everything, but no one has ever explained why this is so bad. I understand what it does but I honestly don't see a huge deal with it.</p>
  
  <p>Anyone care to explain? In my mind it just makes typing <code>cout</code> a whole lot more bearable than <code>std::cout</code>.</p>
  
  <p>I can <em>understand</em> why you wouldn't want to put it in a header file, but just in a normal implementation file... I dont see why it would be a problem.</p>
