Link Nodes Practice Exercises
=============================

createList
----------

.. extrtoolembed:: 'createList'
   :workout_id: 428



One can easily write a loop to iterate through all the Links on a
chain, without needing to know how many there actually are.

.. inlineav:: linkNodes3CON ss
   :links: AV/Pointers/linkNodes3CON.css
   :scripts: AV/Pointers/linkNodes3CON.js
   :output: show
   :keyword: Pointers; Link Nodes


iterateOverList
---------------

.. extrtoolembed:: 'iterateOverList'
   :workout_id: 426



One can remove a Link from a chain.

.. inlineav:: linkNodes4CON ss
   :links: AV/Pointers/linkNodes4CON.css
   :scripts: AV/Pointers/linkNodes4CON.js
   :output: show
   :keyword: Pointers; Link Nodes


changePointeeNext1
------------------

.. extrtoolembed:: 'changePointeeNext1'
   :workout_id: 424




Finally, we can also insert new Links.

.. inlineav:: linkNodes5CON ss
   :links: AV/Pointers/linkNodes5CON.css
   :scripts: AV/Pointers/linkNodes5CON.js
   :output: show
   :keyword: Pointers; Link Nodes


addNodeAtHead
-------------

.. extrtoolembed:: 'addNodeAtHead'
   :workout_id: 429
