Navigating C++ and Object-Oriented Design

Chapter 13. Exception Handling

Designing correct classes and functions is hard work, but making them handle errors properly is even tougher. Most library designers face two major obstacles with error handling:

1.	What kinds of problems can I expect when clients misuse my classes and functions?
2.	What actions do I take once I detect these problems?

Error handling is an important step in the design of classes and functions because we can't always be sure that applications will use our objects or call our functions correctly. Rather than add error handling to working code as an afterthought, you need to make error handling an integral part of the design process.

To help with portability and the design of libraries, C++ includes a language-supported ...
