I thought this would be really simple but it\'s presenting some difficulties. If I have

std::string name = \"John\";
int age = 21;

How do I

    #include 
    #include 
    using namespace std;
    string concatenate(std::string const& name, int i)
    {
        stringstream s;
        s << name << i;
        return s.str();
    }
