What are Containers/Adapters? C++

Question

What are containers/adapters? I have basic knowledge of C++ and its sub-topics like (class/templates/STL).

Can anyone please explain in layman\'s language and give me

Answer 1

C++ is technical and hard to understand :-D

Containers are data types from STL that can contain data.

Example: vector as a dynamic array

Adapters are data types from STL that adapt a container to provide specific interface.

Example: stack providing stack interface on top of the chosen container

(side note: both are actually templates not data types, but the definition looks better this way)
