title: how to jump back to the top of a program
body: <p>I have a large block of code inside main and would like to return to the top of main and run through again if a certain variable in 'code' is true. How would I do this?</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  
  void main(void)
  {
  
  // if varable in code is true return to here
  
  
  
  //code
  //
  //
  //
  
  
  }
  </code></pre>
