C++ template won't accept iterators
===

I'm re-learning C++, and have started by trying what should be a simple algorithm: QuickSort. My function has this signature:

    template <class T>
    void QSort(typename std::vector<T>::iterator begin, typename std::vector<T>::iterator end)

And it is called in my main function:

    int main()
    {
        std::vector<int> unsort({56,32,11,45,67,81,12,5});
        std::vector<int>::iterator b=unsort.begin();
        std::vector<int>::iterator e=unsort.end();
        QSort(b, e);
        return 0;
    }

And gives this error:

    C:\Users\Deus\Projects\QSort\main.cpp||In function 'int main()':|
    C:\Users\Deus\Projects\QSort\main.cpp|49|error: no matching function for call to 'QSort(__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >&, __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >&)'|
    ||=== Build finished: 1 errors, 0 warnings ===|


It seems that the compiler is having trouble resolving what T should be. Is there a way to do what I'm trying to do, or should I just declare the arguments as type T, and work with the resulting uncertainty?
