title: Error in post incement of a preincremented variable (++i)++?
body: <p>In the following code segment, I was expecting the answer to be 5 but it shows compile time error:</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  int main()
  {
      int i = 4;
      printf("%d", (++i)++);
      return 0;
  }
  </code></pre>
  
  <p>What is the reason?. Here <code>++i</code> returns an l value right So we could increment it right?  </p>
