Retourne la paire désadaptation d'abord des éléments de deux gammes: celle définie par [first1, last1) et un autre à partir de first2. La première version de la fonction utilise operator== de comparer les éléments, la deuxième version utilise le prédicat binaire donné p .
Original:
Returns the first mismatching pair of elements from two ranges: one defined by [first1, last1) and another starting at first2. The first version of the function uses operator== to compare the elements, the second version uses the given binary predicate p.

first1, last1 -
la première plage des éléments
Original:

Original:

p - binary predicate which returns ​true if the elements should be treated as equal.

The signature of the predicate function should be equivalent to the following:

 bool pred(const Type1 &a, const Type2 &b);

The signature does not need to have const &, but the function must not modify the objects passed to it.
The types  Type1 and  Type2 must be such that objects of types InputIt1 and InputIt2 can be dereferenced and then implicitly converted to  Type1 and  Type2 respectively.

Type requirements
-
InputIt1 must meet the requirements of InputIterator.
-
InputIt2 must meet the requirements of InputIterator.
-
OutputIt must meet the requirements of OutputIterator.

[modifier] Retourne la valeur

std::pair avec les itérateurs aux deux premières non équivalents éléments, ou, si aucun des différents éléments trouvés, paire avec last1 et l'itérateur correspondant de la deuxième plage .
Original:
std::pair with iterators to the first two non-equivalent elements, or, if no different elements found, pair with last1 and the corresponding iterator from the second range.

[modifier] Mise en œuvre possible

First version
template<class InputIt1, class InputIt2>
std::pair<InputIt1, InputIt2>
    mismatch(InputIt1 first1, InputIt1 last1, InputIt2 first2)
{
    while (first1 != last1 && *first1 == *first2) {
        ++first1, ++first2;
    }
    return std::make_pair(first1, first2);
}
Second version
template<class InputIt1, class InputIt2, class BinaryPredicate>
std::pair<InputIt1, InputIt2>
    mismatch(InputIt1 first1, InputIt1 last1, InputIt2 first2, BinaryPredicate p)
{
    while (first1 != last1 && p(*first1, *first2)) {
        ++first1, ++first2;
    }
    return std::make_pair(first1, first2);
}
