title: Find the next leap year in C
body: <p>I'm having trouble with an exercise on my homework.
  I have to make a function that tells me when the next leap year is given an <code>n</code> (or <code>n</code> if it's a leap year).</p>
  
  <p>I already tackled the last part, but I'm having trouble with the "next leap year" part. I assume I have to do a cycle? </p>
  
  <p>Here's what I have so far</p>
  
  <pre><code>int next_leapyear(int n) 
  {
  
      if(((n%4==0)&amp;&amp;(n%100!=0))||(n%400==0)) return n;
  
      else
      while(?){
        n++;
       }
  
       return n;
  }
  </code></pre>
  
  <p>I'm just starting to learn this language, so if you guys could keep it simple I would appreciate it</p>
