A Standard Template Library (STL) is a library of container templates approved by the ANSI committee for inclusion in the standard C++ specification. We have various types of STL containers depending on how they store the elements.
Queue, Stack – These are the same as traditional queue and stack and are called adaptive containers.
Set, Map – These are basically containers that have key/value pairs and are associative in nature.
Vector, deque – These are sequential in nature and have similarities to arrays.
