advance

template<class InIt, class Dist>
    void advance(InIt& it, Dist n);

The template function effectively advances it by incrementing it n times. If InIt is a random-access iterator type, the function evaluates the expression it += n. Otherwise, it performs each increment by evaluating ++it. If InIt is an input or forward iterator type, n must not be negative.
