mismatch

The function mismatch is used to find sequences that are not the same or differ according to the predicate criteria.

  template<class InputIterator1, class InputIterator2>
  pair<InputIterator1, InputIterator2> mismatch
  (InputIterator1 first1, InputIterator1 last1,
  InputIterator2 first2);
  template<class InputIterator1, 
  class InputIterator2, class BinaryPredicate>
  pair<InputIterator1, InputIterator2> mismatch
  (InputIterator1 first1, InputIterator1 last1,
  InputIterator2 first2, BinaryPredicate pred);

Remarks

Returns a pair<iterator> that represent the beginning element and the range. If no mismatch is found the end and the corresponding range element is returned.
