ostream utilisation iterator en C++

Question

ici est le code

#include <iostream> 
#include <string> 
#include <algorithm> 
#include <vector> 
#include <fstream> 
#include <iterator> 
using std::vector; 
using std::string; 
using std::cout; 
using std::cin; 
using std::ostream_iterator; 
using std::cout; 

int main(){ 
    vector <string> me; 
    string s; 
    while ((cin>>s) && s!="end") 
     me.push_back(s); 

    std::copy(me.begin(),me.end(), 
     std::ostream_iterator(cout,"\n")); 



    return 0; 
}

Answer 1

ostream_iterator a besoin d'un argument modèle; utilisez ostream_iterator<string> dans ce cas.

Answer 2

J'écris cet exemple.

// ostream_iterator example 
#include<iostream> 
#include<iterator> 
#include<string> 
#include<vector> 
using namespace std; 

int main(void) 
{ 
    vector<string> svec; 
    string mystr; 

    cout << "Enter the strings (Ctrl + Z to end):"; 
    while(cin >> mystr) 
    { 
    svec.push_back(mystr); 
    } 

    ostream_iterator<string> out_it(cout, "\n"); // be careful. not like yours 
    copy(svec.begin(), svec.end(), out_it); 

    return 0; 
} 

Je le complète bien.
