1
Q
Types of composite values
A
- Record Types
- Union Types
- Collections (arrays, lists, maps)
- Recursive types (trees, graphs)
2
Q
Composite values are made up of
A
clearly identifiable components, each of which can be either primitive or composite.
3
Q
A composite type describes a
A
family of composite values, all of which typically have a similar structure.
4
Q
Records are
A
mappings from component names to components
5
Q
A Java object viewed only as a collection of its attributes
A
is an example of a record.
6
Q
Tuples are like records except that
A
their components have no names.
7
Q
Values cannot be modified in Haskell
A
only constructed
8
Q
Ada, Haskell provide pure records and unions with
A
good compile-time type-checking
9
Q
C is flexible but very
A
little type-checking harms safety
10
Q
Haskell supports the extraction of multiple components from records and unions using
A
pattern matching
