Exception
handling is difficult to do well.
|
|
| • |
The
exception handling facilities of C++ provide
|
|
|
mechanisms
to separate error detection from error
|
|
|
processing.
|
|
| • |
This
can significantly improve the organization and
|
|
|
reusability
of our software.
|
|
| • |
However,
it is not a substitute for careful design.
|
|
| • |
Designing
software must include considering both normal
|
|
|
processing
and error processing.
|
|
| • |
When
exception handling is poorly used, it can create more
|
|
problems
than it solves by creating a false sense of
|
|
|
security.
|
|
| • |
On
the other hand, if used properly, it can improve the
|
|
|
robustness,
maintainability, and reusability.
