derived type
     
         A {type} constructed from {primitive types} or
        other derived types using a {type constructor function}.  This
        term is usually applied to {procedural languages} such as {C}
        or {Ada}.  C's derived types are the {array}, {function},
        {pointer}, {structure}, and {union}.
     
        Compare {derived class}.
