C++ Data Structures & STL

This lesson is part of C++ · All levels

Summary

Data structures are a way of organizing data in memory for easy access and processing, from simple structures to dynamic collections. C++ provides a Standard Template Library (STL) consisting of a container (data store), an iterator (element pointer), and an algorithm (common operations such as sort and find). With STL, many data storage and processing problems don't have to be written from scratch.

Key points

The three pillars of STL: container, iterator, and algorithm.
Sequential containers such as vectors and lists maintain order; associative containers such as sets and maps group by key.
Struct is suitable for combined data of various types with little behavior.
Select the container according to the access requirements: random access using vectors, quick insertion in the middle of the list.
