Iterators

Iterators should be written as follows:

• For input iterators, use:

template<typename InIt>

• For output iterators, use:

template<typename OutIt>

• For forward iterators, use:

template<typename FwdIt>

• For bidirectional iterators, use:

template<typename BidIt>

• For random access iterators, use:

template<typename RandIt>
