Defines several types and functions related to the handling of exceptions. Exception handling is used in situations in which the system can recover from an error. It provides a means for control to be returned from a function to the program. The objective of incorporating exception handling is to increase the program's robustness while providing a way to recover from an error in an orderly fashion.
