== Post-Increment==<br />
<br />
<p>The post-increment operator appears directly after the variable.</p><br />
<p>The operation begins by incrementing the variable by 1.</p><br />
<p>The post-increment operator returns the original value before it was incremented.</p><br />
<p>If either of the values is a string, an attempt is made to convert the string to a number.</p><br />
