Hyperlinks in Xampp

I’m still learning Wp and have a couple of sites on line. I wanted to practice in Xampp so I copied all the existing files from CPanel of my host to a folder in the htdocs folder in Xampp and the db to a new db in phpMyAdmin then made the necessary adjustments to the wp-config file. When I view the site at localhost/myWebsite, the hyperlinks point to the main site on line and not the local version. Can anyone help?
