If it's a square taper crank that's come off, be advised that they often get damaged by wobbling around, to the point where thay can't be made to stay in place securely afterwards. That case, you'd have to replace it.
If the loop of the chain is broken you will either need a so-called quick/master link or a chain breaker tool. Quick/master links can be opened and clsoed w/o any special tools, but if your chain didn't come with one(or has broken somewhere else, you will still need a chain breaker tool to clean up the broken link.
Do note that chains needs to be a certain length. Removing damaged links can lead to damage to the bike if you try to force the chain into a gear it can't reach.
If the chain has simply come off the sprockets, just lift it back on.
That'd be the crank arm.
