C++: Standard Template Library (STL)

Standard Template Library (STL) is a C++ library of container classes,algorithms and iterators.It provides many of the basic algorithms and data structures.
STL is a generic library, meaning that its components are heavily parameterized: almost every component in the STL is a template.

STL can be categorized into the following types:

1. sequence containers (vector,qeque,list)
2. associative containers (set,multiset,map,multimap)
3. container adaptors (queue,priority_queue,stack)
4. Other types of containers (bitset,valarray)
