C++ Problem with a class template

Why won't this template compile?

template <class K, class V = Referenced>
class Cache
{
public:
    Cache();
    ...
};

template <class K, class V>
Cache::Cache()   <====  location of compiler error (see below)
{
    ...
}

ERROR error: 'template<class K, class V> class Cache' used without template parameters

Try this:

template <class K, class V>
Cache<K, V>::Cache()
{
    ...
}

Notice the template parameters following the class name.

You need to specify the template parameters:

template <class K, class V>
Cache<K, V>::Cache()
{
    ...
}
