Exceptions are used to signal errors or unexpected conditions in a program. While other error-handling mechanisms do exist, exceptions generally lead to simpler, cleaner code, in which you are less likely to miss an error. Particularly in combination with the RAII principle (short for “resource acquisition is initialization”), we will show that exceptions form the basis of some of the most effective programming patterns in modern C++.
In this chapter, you’ll learn:
What an exception is and when ...
