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.
