流迭代器初识

#include <iostream>

using namespace std;
 
int main()
{
    vector<int> a;
    vector<int>::iterator iter;
    for (int i=0; i<10; i++)
        a.push_back(i);

    ostream_iterator<int> oo(cout, "\n"); //定义一个oo对象
    copy(a.begin(), a.end(),oo); //输出数据到cout

    copy(a.begin(), a.end(), ostream_iterator<int>(cout, "\n"));//构造一个临时对象
 
    system("pause");
    return 0;
