You can do so by using the server URL to your account. It is of type:

http://servername.com/~username/

where:

servername.com is the actual server name where your account is located. You can get this from the name servers provided for your domain name.
username is the exact cPanel username for your account.

You can make a WordPress installation via cPanel -> Softaculous. Once you have done so, you should also change the siteurl and home options in your WordPress database. You can do this using the phpMyAdmin tool available in your cPanel.

Once in phpMyAdmin, select your WordPress database and browse the table wp_options. Find the options siteurl and home and change their values to the server name URL for your account.
