using namespace std;

int main(int argc, char* argv[])
{
    //vector initialization list
    vector<int> vec = {6, 7, 8};

    //auto data type, range-based for loop using colon
    for(auto elt : vec)
    {
        cout << elt << " ";
    }
    cout << endl;

    //convert from int to string
    //error: 'to_string' function is not available yet
    //string s1 = to_string(vec[2]);
    stringstream ss;
    ss << vec[2];
    string s1 = ss.str();
    cout << s1 << endl;

    //convert from string to int
