Singly-linked list/Element definition: Difference between revisions

== Icon and Unicon ==

The Icon version works in both Icon and Unicon. Unicon also permits a class-based definition.

=== {{header|Icon}} ===

<lang Icon>

record Node (value, successor)

</lang>

=== {{header|Unicon}} ===

<lang Unicon>

class Node (value, successor)

initially (value, successor)

self.value := value

self.successor := successor

end

</lang>

With either the record or the class definition, new linked lists are easily created and manipulated:

<lang Icon>

procedure main ()

n := Node(1, Node (2))

write (n.value)

write (n.successor.value)

end

</lang>
