从STL复制功能以打印出矢量

Question

I'm trying to print out vector elements with copy function from STL. Theoretically it supposed to work without any malfunction, but I got weird notification, I google it but I really can't comprehend what failure did I make. Let me show what I'm on about:

#include <iostream> 
#include <vector> 

int main(void)
{
   vector<string> names; 
   names.push_back("Jeremy"); 
   names.push_back("James"); 
   names.push_back("Richard"); 

   copy(names.begin(), names.end(), ostream_iterator<string>(cout, ' '); 

   // this line cause some problems;


}

I got the following error:

invalid conversion from const char*' to char'

I would love to obtain some proper (easy to understand as well) explanation what is wrong with my idea ;)

Cheers!

Answer 1

1.Change:

copy(names.begin(), names.end(), ostream_iterator<string>(cout, ' ');

into:

copy(names.begin(), names.end(), ostream_iterator<string>(cout, " "));

(string literal, not character)

2.add missing paren.

3.and add missing <algorithm> , <iterator> and <string> headers.

4.add using namespace std;
