C++ 流迭代器

输出流迭代器

#include<iostream>
#include<iterator>
#include<algorithm>
#include<vector>

using namespace std;

int main()
{
    int sz[6] = { 1, 2, 3, 4, 5, 6 };
    vector<int> ob(sz, sz + 6);
    ostream_iterator<int, char>osi(cout, " ");
    copy(ob.begin(), ob.end(), osi);
    cout << endl;
    return 0;

}
