You can use topic diagrams to create dynamic views of
relationships between existing C/C++ elements based on queries (topic
context).
You can use topic diagrams to explore entire
inheritance hierarchy and associations of C/C++ classes and interactions
of C/C++ methods. You can save topic diagrams as UML class diagrams
that you can use to visually understand and develop your C/C++ applications.
You
can customize a query for an existing topic diagram to change its
context or level of detail.
