Explicit
conversions occur when the client explicitly
|
|
|
invokes
a cast operation.
|
|
|
| • |
Both
implicit and explicit type conversions result in a
|
|
|
temporary
object of the type being converted to.
|
|
|
| • |
This
temporary object is used in place of the original.
|
|
|
| • |
The
value of the original object is not affected.
|
|
|
| • |
When
considering execution efficiency, it is important to
|
|
|
reduce
or minimize the creation of such temporaries.
|
|
|
| • |
We
recommend minimizing user defined conversions as
|
|
|
much
as possible by avoiding mixed type expressions and
|
|
by
supplying arguments to functions that exactly match
|
|
|
the
type required by the function prototypes.
