Why does this function not deduce template arguments?

[JUANDENT]

I have a template function like this:

template <typename T, template <typename> typename Container>
void sortContainer(Container<T>& cont)
{
	std::sort(cont.begin(), cont.end());
}

types cannot be deduced as in the following:

void useSortContainer()
{
	std::vector v{8, 4, 90, 12, -34};
	sortContainer<int, std::vector>(v);
        sortContainer(v); // THIS does not compile!
}

Thanks,
Juan

std::vector has two template type parameters.

template<typename T, typename A, template <typename,typename> class Container >
void do_sort( Container<T,A>& cntr ) { std::sort( cntr.begin(), cntr.end() ) ; }
