template <class ForwardIterator, class T>
void iota(ForwardIterator first, ForwardIterator last, T value);
Requires: T shall be convertible to ForwardIterator's value type. The expression ++val, where val has type T, shall be well formed.
Effects: For each element referred to by the iterator i in the range [first,last), assigns *i = value and increments value as if by ++value.
Complexity: Exactly last - first increments and assignments.
