Derived Types

Derived Types

Derived types are user-defined data types based on the intrinsic types, INTEGER, REAL, COMPLEX, LOGICAL, and CHARACTER. Where an array is a set of data all of the same type, a derived type can be composed of a combination of intrinsic types or other derived types. A data object of derived type is called a structure.

In the following sections, these topics are covered:

• Derived Type Definitions describes defining the structure of a user defined data type.
• Declaring Derived Type Variables shows examples of declaring derived type variables.
• Derived Type Constructors describes initialization of derived type data
