sort

template <class RandIter>    void sort(RandIter start, RandIter end);template <class RandIter, class Comp>     void sort(RandIter start, RandIter end, Comp cmpfn);

The sort( ) algorithm sorts the range specified by start and end.

The second form allows you to specify a comparison function that determines when one element is less than another.
