    Syntax:

  <pre class="syntax-box">
  #include &lt;cstring&gt;

</pre>

  <p>The function strcmp() compares <em>str1</em> and <em>str2</em>,
  then returns:</p>

  <table class="code-table">
    <tr>
      <th class="code-table-th">Return value</th>

      <th class="code-table-th">Explanation</th>
    </tr>

    <tr>
      <td class="code-table-td">less than 0</td>

      <td class="code-table-td">&#39;&#39;str1&#39;&#39; is less than
      &#39;&#39;str2&#39;&#39;</td>
    </tr>

    <tr>
      <td class="code-table-td">equal to 0</td>

      <td class="code-table-td">&#39;&#39;str1&#39;&#39; is equal to
      &#39;&#39;str2&#39;&#39;</td>
    </tr>

    <tr>
      <td class="code-table-td">greater than 0</td>

      <td class="code-table-td">&#39;&#39;str1&#39;&#39; is greater
      than &#39;&#39;str2&#39;&#39;</td>
    </tr>
  </table>

  <p>For example:</p>
<pre class="prettyprint">
   printf( &quot;Enter your name: &quot; );
   scanf( &quot;%s&quot;, name );
   if( strcmp( name, &quot;Mary&quot; ) == 0 ) {
     printf( &quot;Hello, Dr. Mary!\n&quot; );
   }
</pre>

  <p>Note that if <em>str1</em> or <em>str2</em> are missing a
  null-termination character, then strcmp() may not produce valid
  results.  For a similar (and safer) function that includes explicit
  bounds checking, see <a href="strncmp.html">strncmp()</a>.</p>
