Partial template specialization for arrays

Question

Seached for this, but can\'t find a similar question. If there is one please close this question. This isn\'t my real code, just an example to demonstrate :-

Answer 1

Capture the size with an additional non-type parameter:

#include <iostream>

template <class T> class Test
{
public:
    ~Test() { std::cout << "Normal \n";}
};

template<class T, size_t N> class Test<T[N]>
{
public:
    ~Test() { std::cout << "Array " << N << '\n'; }
};

int main()
{
    Test<int[3]> i;  // Array 3
    Test<int[5]> j;  // Array 5
}
