Do you think an entire application (or at least each class) should have a
'final' try-catch block setup for any unexpected errors that could occur? If
so, how would you set this up? Would you 'throw' the errors to the final
exception block?
If not can you tell me why you would not have a final try-catch block?

Application : yes
Each class : no

Many (read: most) classes will not know how to handle an exception.

Rethrowing is usually an API thing.

Most places.

See above.

In unmanaged code, it's relatively simple to just pre-allocate
everything you need for error reporting, and then be assured that memory
allocations will only ever be attempted under the control of your own
program code.

In C one has a good feeling for memory allocation.

In C++ especially if it is a bit complex then it can
be difficult to understand where all the allocations
are happening.
