If the horn only honked once it may be a symptom of your car alarm being set off after power has been re-applied. If the horn stays on after you reconnect the battery you have either a stuck horn button on your steering wheel or a stuck horn relay. Or it could be the alarm sounding the horn but that usually that occurs in a series of horn blasts (rather than continuous) and the car indicators usually flash in sync with the alarm sounding.
If the horn is stuck on in a continuous blast ie not sounding on and then off and then on etc etc, disconnect one the battery cables then pull the fuse that feeds the horn or pull off one of the removable spade electrical connectors from one of the 2 terminals on the horn itself. Usually the fuse box is either under the dashboard on the drivers side or could be under the hood. Consult your user manual for your car for fuse and horn locations.
If the horn is stuck you need to visit a qualified auto electrician, or perhaps you have a friend who knows his way around auto electrics?
