#include<iostream>
using namespace std;
class test
{
public:
    operator int()
    {
        return i;
    }
    test(int k = 1):i(k)
    {
        cout << "test" << ' ';
    }
    ~test()
    {
        cout << "~test" << ' ';
    }
    int i;
};
int main()
{
    test (*P)[5] = new test[4][5];
    delete []P;
    system("pause");
    return 0;
