/*That’s it! The first parameter passed in is the name of the shortcode, so in our case, ‘adsense’ tells WordPress to create the [adsense] shortcode. The second parameter designates the function that will be called when the new shortcode is encountered. Again, in our case, ‘get_adsense’ tells WordPress to replace [adsense] with the results of our get_adsense method.*/
