iter_swap function template — Swaps values that iterators point to

Synopsis

template<typename FwdIter1, typename FwdIter2>
  void iter_swap(FwdIter1 a, FwdIter2 b);

The iter_swap function template swaps the values pointed to by a and b. You can think of its functionality as:

FdwIter1::value_type tmp = *b*;
*b = *a;
*a = tmp;
