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
- 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
- Double-ended queue
- Priority queue

- Graph
Some properties of abstract data types ("stable" means that input order is retained):
| Structure | Stable | Unique | Cells per Node |
|---|---|---|---|
| List | yes | no | 1 |
| Associative array | no | yes | 2 |
| Set | no | yes | 1 |
| Multiset | no | no | 1 |
