Remember these are potential/possible Job-Interview Questions, so no googling, running it in your compiler etc. Pretend like you're in a conference room with nothing but a white board....

If you don't know the answer, you can simply say so or try to write out what you think it is...

This one is a 3 parter:

A) What is a pure virtual Function?

B)Consider the following code:

Code:

#include <iostream>
using namespace std;

Class A
{
	public:
		A() { this->Foo(); }
		virtual void Foo() { cout << "A::Foo()" << endl; }
};

Class B : public A
{
	public:
		B() { this->Foo(); }
		virtual void Foo() { cout << "B::Foo()" << endl; }
};

int main(int, char**)
{
	B ObjectB;
	return 0;
}

C)What output would it generate if you make A::Foo() a pure virtual function?
