replace_if function template — Replaces values that satisfy a predicate

Synopsis

template<typename FwdIter, typename Predicate, typename T>
  void replace_if(FwdIter first, FwdIter last, Predicate pred, 
                  const T& new_value);

The replace_if function template replaces all values in [first, last) for which pred is true with new_value. See Figure 13-14 (under replace_copy) for an example of the replacement process.

Technical Notes

The replace_if function template assigns *i = pred(*i) ? new_value : *i for all i in [first, last).

Complexity is linear: exactly last - first comparisons are performed.
