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 (for boolean values True/False)
• Char (for character values)
• Float (for storing real number values)
• Double (a larger size of type float)
• int (for integral or fixed-precision values)
• Enumerated type

Composite types

• Array
• Record (also called tuple or struct)
• Union
• Tagged union (also called a variant, variant record, discriminated union, or disjoint union)
• Plain old data structure

Abstract data types

• Container
• Map/Associative array/Dictionary
• Multimap
• List
• Set
• Multiset
• Priority queue
• Queue
• Deque
• Stack
• String
• Tree
• Graph

Some properties of abstract data types:

"Stable" means that input order is retained. Other structures such as "linked list" and "stack" cannot easily be defined this way because there are specific operations associated with them.
