Instancespecific data is stored in the typed object instance, and data or behavior that should be shared across all instances of the same conceptual type is stored in the type object. If t is an object type that is any possibly cvqualified type other than function, reference, or void types, provides the member constant value equal true. A variable is nothing but a name given to a storage area that our programs can manipulate. For example, the following null indicator struct was generated in the example in the previous section. When an object type is selected into a c struct, null indicator information may be selected into a parallel struct. Each variable in objectivec has a specific type, which determines the size and layout of the variables memory. While the object can subsequently be cast to various types, it can never change its runtime type many aspects of type systems.
