title: $display in Verilog and printf in C
body: <p>As you know in <code>Verilog</code> has <code>$display,$strobe</code> and $monitor  those used to display text on the screen.
  And in C has <code>printf</code> to display text on screen also. </p>
  
  <p>My question is how can I use one of them (<code>$display,$strobe,$monitor</code>) like <code>printf</code> in <code>C</code>?</p>
  
  <pre><code>a: $display
  b:$strobe
  c:$monitor
  d: all of them
  e: other
  </code></pre>
