1) Did you mean while executing? The standard exceptions are logic_error, invalid_argument, domain_error, length_error, out_of_range, runtime_error, range_error, overflow_error, underflow_error, bad_typeid, bad_cast, bad_weak_ptr, bad_function_call, bad_alloc, bad_array_new_length, bad_exception, system_error, ios_base::failure, future_error

2) It lets you separate error reporting from error handling.
