Adjacent For Each

template<typename InputIterator, typename Function>
Function adjacent_for_each(InputIterator first, InputIterator last, Function f)

template<typename Range, typename Function>
Function adjacent_for_each(const Range& range, Function f)

template<typename Range, typename Function>
Function adjacent_for_each(Range& range, Function f)

Calls function f for each adjacent pair of elements in a range.

Example

#include <iostream>
#include <boost/algorithm/adjacent_for_each.hpp>

void PrintInts(int a, int b) {
  std::cout << '(' << a << ", " << b << ")\n";
}

int main() {
  const int ints[] = {0, 1, 2, 3, 4};
  boost::algorithm::adjacent_for_each(ints, ints + 5, PrintInts);
}

Output:

(0, 1)
(1, 2)
(2, 3)
(3, 4)
