If you have a server that should process 100000 requests and processing one of them happen to throw an exception, it's very easy to just wrap request->process() with try catch and continue processing the rest of the requests.
You can also use it to recover parts of the processing with sane defaults. String parse integer exception? Use constant 0 instead if that makes sense, etc etc.
I don't see why people make exceptions in c++ into a big deal and a big mystery, in other languages people just use them, the only caveat in c++ is throwing in destructors but that's easy to remember. In one place I worked they had meetings for over a week to discuss whether it was ok or not to throw exceptions in a constructor or not T_T.
