Answer 1

#include <iostream>
using namespace std;
class Base
{
   int m;


public:
   Base()
   {
      cout << "Default constructor in base\n";
   }
};


class Derived : public Base
{
   int n;


public:
   Derived()
   {
      cout << "Default constructor derived\n";
   }
   Derived(int i)
   {
      cout << "Parameterized constructor derived\n";
   }
};
class Alarm{
	public:
		~Alarm();//destructor
};
int main()
{
   Base z;
   Derived x1;
   Derived x2(4);
}
