Questions tagged [containers]

A container is a class, a data structure, or an abstract data type whose instances are collections of other objects. Containers typically make use of generics or templates so that a wide variety of objects can be added.

Containers are available in most programming languages, allowing programmers to store, transfer, and read back data within a program. Common containers include arrays, lists, queues, stacks, sets, and maps, each providing different levels of efficiency for tasks such as adding or removing elements, searching for elements, or iterating through elements.
