Can we make constructor Virtual?
What is Graceful Termination? Give an example.
In both virtual inheritance and multiple inheritance copy/copies of base class are created, List down how many copy/copies are created for:
virtual inheritance
Multiple inheritance
What would be the output of this code?
class mother {
  public:
    mother ()
      { cout "mother: no parameters\n"; }
    mother (int a)
      { cout "mother: int parameter\n"; }
};
class daughter : public mother {
  public:
    daughter (int a)
      { cout "daughter: int parameter\n\n"; }
};
class son : public mother {
  public:
    son (int a) : mother (a)
      { cout "son: int parameter\n\n"; }
};

int main () {
  daughter rabia (0);
  son salman(0);
  return 0;
}
The code given below has one template function as a friend of a template class,

1. You have to identify any error/s in this code and describe the reason for error/s.
2. Give the correct code after removing the error/s.

template<typename U>
void Test(U);
template< class T >
class B {
            int data;
            public: friend void Test<>( T );
};
template<typename U>
void Test(U u){
    B < int> b1;
    b1.data = 7;
    }
int main(int argc, char *argv[])
{
    char i;
    Test(i);
    system("PAUSE");
    return 0;
};
Describe three properties necessary for a container to implement Generic Algorithms.
