You can design C/C++ classes or data types, add fields or methods
to classes or interfaces, or add inheritance or implementation relationships
between C/C++ classes or data types.
Modifying C/C++ classes or data types
You can modify names, fields (attributes), and methods (operations)
of C/C++ classes and data types from class diagrams.
Renaming C/C++ elements
You can rename C/C++ elements, attributes, and operations from
the diagram editor.
Creating relationships between C/C++ elements
Relationships identify the semantic ties that exist between C/C++
elements. To add relationships to a C/C++ class diagram, you must work in
the diagram editor. You cannot specify relationships in the Project
Explorer view.
