What output does the following code generate? Why?
What output does it generate if you make A::Foo() a pure virtual function?
class A {
A() { this->Foo(); }
virtual void Foo() { cout << "A::Foo()" << endl; }
};
class B : public A {
B() { this->Foo(); }
virtual void Foo() { cout << "A::Foo()" << endl; }
};
int main(int, char**)
{
A objectA;
B objectB;
return 0;
}

A research student is given a singly-linked list. Each node of the list has a color, which is either “Black” or “White”. He must find if there are more black nodes than white nodes, or vice versa. His advisor gives him 5,000Rs to buy a computer to do the work. He goes to the computer store and finds a slightly defective computer which costs a mere 3,000Rs. This computer has the small problem of not being able to do arithmetic. This means that he cannot use a counter to count the nodes in the list to determine the majority color. The computer is otherwise fully functional. He has the evil idea that he could buy the defective computer and somehow use it to do his work, so that he can use the rest of the money on enjoyment. Show how he can accomplish this amazing task. Write code for an algorithm called ‘findMajorityColor’ which takes a singly-linked list, L, with n nodes and returns the majority color among nodes of L. This algorithm should have the same asymptotic running time as counting the nodes (O(n)). Note: No arithmetic is allowed.
