title: Converting int to string in C
body: <p>I am using the <code>itoa()</code> function to convert an <code>int</code> into <code>string</code>, but it is giving an error:</p>
  
  <pre><code>undefined reference to `itoa'
  collect2: ld returned 1 exit status
  </code></pre>
  
  <p>What is the reason? Is there some other way to perform this conversion?</p>
