Error in a vector program

MedSWEng (1)
I'm trying to run this simple program in "Visual C++ 2008 Express Edition":

1
2
3
4
5
6
7
8
9
10
 
#include <iostream>
#include <vector>
#include "stdafx.h"

int main(){
std::vector<bool> features(4,false);
for(std::vector<bool>::iterator i = features.begin(); i != features.end(); i++){
std::cout<<features[i];
}
}


When I do that, I get the following:

1

Why is that? And, how can I solve it out?

Thanks.

It has something to with prerecompiled headers and stdafx.h. What happens if you remove the line #include "stdafx.h" ?
