Study Notes

History of STL

  • The Standard Template Library (STL) was originally designed by Alexander Stepanov and Meng Lee at Hewlett-Packard.

Components of STL

  • The STL provides four components: algorithms, containers, iterators, and function objects.

Relationship between Algorithms and Containers

  • STL algorithms operate on containers, but are decoupled from them, allowing for greater flexibility and reusability.

Polymorphism in STL

  • The STL uses templates to provide polymorphism, allowing algorithms and containers to work with different data types.

Origin of STL

  • The STL was created as a collection of generic, reusable containers and algorithms for the C++ programming language.
