in the standard template library.
Some of you should already be using the standard template library.
For example, I recommended earlier that Vector is a really important,
maybe the most important, container class in the standard template library.
And it's very easy to use for anybody who's already familiar with C.
It just replaces in most instances an ordinary C array.
So in the use of the standard template library.
There is a generalization of which you might call a cursor, and
those are called iterators.
And the standard template library is all based on the use of iterators.
I say, well talk about it extensively later on.
