•C++ allows us to detect error conditions at any point in a program (the throw point) and then transfer control and information (the exception) to another point in the program (the exception handler) for
error processing.
•This process (exception handling) allows functions to detect error conditions and then defer the processing
or handling of those
error conditions to a direct or indirect
caller of those functions.
•Exception handling allows us to separate normal processing from error processing.
•This, in turn, improves the structure, organization, and reusability of our software.
