An InstanceVariable is a Field that shares the lifetime of object instances whose type is the Classifier they are associated with. Examples include non-static fields in C++ and Java, and fields of structs in C.
Specification

|---|---|
| Extends | Field |
| Description | A Variable associated with instances of a Classifier. |
