Line 5:

For example, given a skeleton for common operations on data structures, there may be a few common operations and some specific to the data structure. The data structure template class can provide a template for each newly added data structure class.

<pre>

class CDatastructure_Template

{

Line 16 ⟶ 15:

Node* virtual GetNextNode(Node *CurrentNode)=0;

};

class CLinkList_ConcTemplate:public Datastructure_Template;

Line 24 ⟶ 23:

class CTree_ConcTemplate:public Datastructure_Template;

</pre>

New data structure class can be derived from the <tt>CLinkList_ConcTemplate</tt>, with operations modified as necessary.
