For showing the facebook and twitter button in wordpress post many times we need to install the various plugins but with following code you dont need to install the wordpress plugin.

If you are wordpress developer then only use following code. Open your functions.php file from your theme and put following code in that file.

function facebook_twitter_button($content){
    if(!is_feed() && !is_home()) {
        $content .= '<div class="facebook-twitter-button">
                    <a href="http://twitter.com/share"
class="twitter-share-button"
data-count="horizontal">Tweet</a>
                    <script type="text/javascript"
src="http://platform.twitter.com/widgets.js"></script>
                    <div class="facebook-share-button">
                        <iframe
src="http://www.facebook.com/plugins/like.php?href='.
urlencode(get_permalink($post->ID))
.'&amp;layout=button_count&amp;show_faces=false&amp;width=200&amp;action=like&amp;colorscheme=light&amp;height=21"
