Hello Gili

Container is a data structure that  *contains* other objects. For example,
your Array<int> above is a container of ints.

Simple C arrays are also containers since they contain objects of their
element type.
The standard library has many container classes (all in the form of a
template)
for example:   vector,  list, deque, set, and many more.
