std::insert_iterator是一个输出迭代器，它被构造，在该位置到一个容器中插入元素指出，由所提供的迭代器，使用容器的insert()每当迭代器（不论是否解除引用或不）被分配到的成员函数。递增std::insert_iterator是一个no-op.

Original:

std::insert_iterator is an output iterator that inserts elements into a container for which it was constructed, at the position pointed to by the supplied iterator, using the container's insert() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::insert_iterator is a no-op.

为例

#include <vector>
#include <list>
#include <iostream>
#include <iterator>
#include <algorithm>
int main()
{
    std::vector<int> v{1,2,3,4,5};
    std::list<int> l{-1,-2,-3};
    std::copy(v.begin(), v.end(), // may be simplified with std::inserter
              std::insert_iterator<std::list<int>>(l, std::next(l.begin()))); 
    for(int n : l)
        std::cout << n << ' ';
    std::cout << '\n';
}

Output:

-1 1 2 3 4 5 -2 -3
