title: Strange definitions of TRUE and FALSE macros
body: <p>I have seen the following macro definitions in a coding book.</p>
  
  <pre><code>#define TRUE  '/'/'/'
  #define FALSE '-'-'-'
  </code></pre>
  
  <p>There was no explanation there.</p>
  
  <p>Please explain to me how these will work as <code>TRUE</code> and <code>FALSE</code>.</p>
