catching and re-throwing exceptions in c++

I am a java developer trying to maintain some very old c++ code (still have to use vs2010 to compile).

I am at home trying to understand exceptions without the ability to test stuff, so sorry if this question is stupid.

Can you throw an exception in a low level function and just catch it at the top, or does it have to be caught and re-thrown at every level?

This is complicated by the fact i am writing native code, calling managed code, calling c#, calling my java rest resource. So are there any levels in there I absolutely have to catch and convert then re-throw.

Thank you in advance.

Edit: as Jesper has answered the first half, can my native code handle system::exception?
