#include <iostream>

	void show();
};
int main()

		for (int j = 0; j < 3; j++)
			for (int k = 0; k < 3; k++)
				_3darray[i]._array[j][k] = k;   //对三维数组赋值

	for (int i = 0; i < 3; i++)
		_3darray[i].show();   //输出三维数组
	system("pause");
    return 0;  
}

void _2darray::show()

	for (int i = 0; i < 3; i++)

		for (int j = 0; j < 3; j++)
			cout << _array[i][j] << " ";
		cout << endl;
