Exceptional C++: 47 Engineering Puzzles, Programming Problems, and Solutions

Chapter 12. Writing Exception-Safe Code—Part 5

Difficulty: 7

All right, you've had enough rest—roll up your sleeves, and get ready for a wild ride.

Now we're ready to delve a little deeper into the same example, and write not just one but two new-and-improved versions of Stack. Not only is it, indeed, possible to write exception-safe generic containers, but by the time this miniseries is over, we'll have created no fewer than three complete solutions to the exception-safe Stack problem.

Along the way, we'll also discover the answers to several more interesting questions:

• How can we use more-advanced techniques to simplify the way we manage resources and get rid of the last try/catch into the bargain?

• How can we improve Stack by reducing the requirements ...
