Eclipse CDT ranged for

I'm trying to write an answer to an exercise in the C++ Primer. Here is my
code:
int main()
{
vector<int> v1;
vector<int> v2(10);
vector<int> v3(10, 42);
vector<int> v4{10};
vector<int> v5{10, 42};
vector<string> v6{10};
vector<string> v7{10, "hi"};
for(auto i : v2)
cout << v2[i] << " " <<;
return 0;
}
The problem is that I'm getting a generic "syntax error" at the for loop.
I've tried all combinations of declaring i as int and declaring &i, but no
luck. The book made a similar for loop like so:
vector<int> v{1, 2, 3, 4, 5, 6, 7, 8, 9};
for (auto &i : v)
i *= i;
for (auto i : v)
cout << i << " ";
cout << endl;
What am I doing that's different?
