find_if function template — Searches for when a predicate returns true

Synopsis

template<typename InIter, typename Predicate>
  InIter find_if(InIter first, InIter last, Predicate pred);

The find_if function template (similar to find) searches the range [first, last) for the first item for which pred(*iter) is true. It returns an iterator that points to the matching item. If no matching item is found, last is returned.

Technical Notes

The find_if function template returns i = first + n, in which n is the smallest value such that pred(*(first + n), value) is true. If there is no such n, i = last.

Complexity is linear: pred is called at most last - first times.
