List of data structures
This is a list of data structures. For a wider list of terms, see list of terms relating to algorithms and data structures. For a comparison of running time of subset of this list see comparison of data structures.
Data types
Primitive types
- Boolean, true or false
- Character
- Floating-point, single-precision real number values
- Double, a wider floating-point size
- Integer, integral or fixed-precision values
- Enumerated type, a small set of uniquely-named values
Composite types or Non-primitive type
- Array
- Open Array
- Record (also called tuple or struct)
- Union
- Tagged union (also called variant, variant record, discriminated union, or disjoint union)
Abstract data types
- Container
- List
- Associative array
- Multimap
- Set
- Multiset
- Stack
- Queue

Some properties of abstract data types:
| Structure | Order | Unique |
|---|---|---|
| List | yes | no |
| Associative array | no | yes |
| Set | no | yes |
| Multiset | no | no |
