how to identify partial template specilization

I am studying templates where I find this example : 

template <typename T, int size>
void print(StaticArray<T, size> &array)
{
    for (int count = 0; count < size; ++count)
        std::cout << array[count] << ' ';
}


template <int size>
void print(StaticArray<char, size> &array)
{
    for (int count = 0; count < size; ++count)
        std::cout << array[count];
}

Why second print function works even though it is having non-type parameter size and why it is full template specialization.

No, this is not specialization, but function template overloads, which take different template parameters.

As you said, the 2nd overload still has a template parameter, so it's not a full specialization. And partial specialization is not allowed for function template; it only works with class templates.
