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

Chapter 11. Writing Exception-Safe Code—Part 4

Difficulty: 8

Mid-series interlude: What have we accomplished so far?

Now that we have implemented an exception-safe and exception-neutral Stack<T>, answer these questions as precisely as possible:

1. What are the important exception-safety guarantees?

2. For the Stack<T> that was just implemented, what are the requirements on T, the contained type?

Solution

Just as there's more than one way to skin a cat (I have a feeling I'm going to get enraged e-mail from animal lovers), there's more than one way to write exception-safe code. In fact, there are two main alternatives we can choose from when it comes to guaranteeing ...
