标准输入输出流

调戏林黛玉

#include<iostream>
#include<vector>
#include<iterator>
#include<algorithm>
using namespace std;
int main()
{
   
   istream_iterator<int> cin_it(cin);  // reads ints from cin
   istream_iterator<int> end_of_stream;   // end iterator value
   // initialize vec from the standard input：
   vector<int> vec(cin_it,end_of_stream);      
   sort(vec.begin(),vec.end());
   //write ints to cout using " " as the delimiter
   ostream_iterator<int> output(cout," ");
   //write only the unique elements in vec to the standard output
   unique_copy(vec.begin(),vec.end(),output);
   
   return 0;
   }





为什么这个运行时没有输出呢？
