std::front_insert_iterator是输出预先考虑元素的迭代器，它被修建的容器，使用时容器的push_front()成员函数的迭代器（是否解除引用或不）被分配给的。递增std::front_insert_iterator是一个no-op.

Original:

std::front_insert_iterator is an output iterator that prepends elements to a container for which it was constructed, using the container's push_front() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::front_insert_iterator is a no-op.

#include <iostream>
#include <iterator>
#include <algorithm>
int main()
{
    std::vector<int> v{1,2,3,4,5};
    std::deque<int> d;
    std::copy(v.begin(), v.end(),
              std::front_insert_iterator<std::deque<int>>(d)); // or std::front_inserter(d)
    for(int n : d)
        std::cout << n << ' ';
    std::cout << '\n';
}
