If you don't mind typing, there is a complete class (with excellent annota-
tion) in 
	Tony L. Hansen, The C++ Answer Book, Addison-Wesley 1990 (!)
When I first heard about the book ("solves all exercises in Stroustrup"), I 
thought "who cares." But Andrew Koenig recommended it and I bought a copy.
It is an excellent book. It does far more than solve all the exercises.
There are lots of very good hints and comments. Recommended. And not even
over-priced. (At least not when compared with A. Koenig's C Traps & Pitfalls
:-))
