The STL Library #

STL is a library of C++ template classes to provide common programming data structures and functions. STL has 4 major components:

• Containers
• Iterators
• Algorithms
• Function Objects

Containers #

Sequence Containers #

Associative Containers #

Unordered Containers #

Unordered containers lack an order thus can be visualized as a bag filled with elements. Unordered elements use a hash function to map keys with their values.

Container Adaptors #

Container adaptors acts as an interface to provide functionality to pre-existing containers. They are implemented as a wrapper around another container.
