title: What is the printf format specifier for bool?
body: <p>Since ANSI C99 there is <code>_Bool</code> or <code>bool</code> via <code>stdbool.h</code>. But is there also a <code>printf</code> format specifier for bool?</p>
  
  <p>I mean something like in that pseudo code:</p>
  
  <pre><code>bool x = true;
  printf("%B\n", x);
  </code></pre>
  
  <p>which would print:</p>
  
  <pre><code>true
  </code></pre>
