|
| • | With
reference parameters, the argument and the |
||||||||
| parameter
become synonyms for the same |
|||||||||
| memory
location, but only during a particular call |
|||||||||
| to
the function. |
|||||||||
| • | With
value parameters, implicit type coercion |
||||||||
| occurs
if the matched items have different data |
|||||||||
| types.
In contrast, with reference parameters, the |
|||||||||
| matched
items must have exactly the same type. |
