C++ Standard Template Library

The C++ Standard Template Library (STL) is a collection of ready-made tools that help programmers handle common data tasks efficiently. It provides reusable templates for data structures like vectors (dynamic arrays), lists, and maps (key-value pairs), as well as algorithms for sorting, searching, and manipulating data. By using these templates, developers can write flexible, high-performance code without building these components from scratch. Essentially, STL accelerates programming, promotes code reuse, and ensures reliable, tested solutions for managing data in C++.
