Summary

In this chapter, we have begun expanding our C++ programming repertoire beyond OOP language features to include features that will enable us to write more robust programs. User code can inevitably be error-prone by nature; using language supported exception handling can help us achieve less buggy and more reliable code.

We have seen how to utilize the core exception handling features with try, throw, and catch. We’ve seen a variety of uses of these keywords – throwing exceptions to outer handlers, using an assortment of handlers featuring various types, and selectively grouping program elements together within a single try block, for example. We have seen how to register our own functions with set_terminate() and set_unexpected(). We have seen how to utilize the existing C++ Standard Library exception hierarchy. We have additionally explored defining our own exception classes to extend this hierarchy.

We have added key features to our C++ skills by exploring...
