Resetting C++-mode locally

[Torsten Bronger]

Halloechen!

I write my programs in CWEB which contains C++ and TeX code alternately.
This confuses the c++-mode very much.  I try to avoid that by inserting
e.g. extra apostrophes , parentheses, and semicolons in a construct that
is ignored by TeX and C++.  But it doesn't work always.

How can I reset the status of the c++-mode locally before each C++
fragment?

Tschoe,
Torsten.
