boost::algorithm::erase_tail_copy — Erase tail algorithm.
// In header: <boost/algorithm/string/erase.hpp> template<typename OutputIteratorT, typename RangeT> OutputIteratorT erase_tail_copy(OutputIteratorT Output, const RangeT & Input, int N); template<typename SequenceT> SequenceT erase_tail_copy(const SequenceT & Input, int N);
Remove the tail from the input. The tail is a suffix of a sequence of given size. If the sequence is shorter then required, the whole string is considered to be the tail. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator.
