You have a class Parent with a virtual method a and a class Child that implements a. You also have a several functions:

void f1(Parent p) { p.a(); }
void f2(Parent* p) { p->a(); }
void f3(Parent& p) { p.a(); }

When called with a Child instance, which method will be invoked for f1, f2 and f3?

Explain in detail what the following C++ code does:

#include <iostream>
using namespace std;

template <class T>
T GetMax (T a, T b) {
  T result;
  result = (a>b)? a : b;
  return (result);
}

int main () {
  int i=5, j=6, k;
  long l=10, m=5, n;
  k=GetMax<int>(i,j);
  n=GetMax<long>(l,m);
  cout << k << endl;
  cout << n << endl;
  return 0;
}

What is the difference between pointer and reference? Please describe the two main differences.

Define the following object oriented concepts:

• Class, object (and the difference between the two)
• Instantiation
• Method (as opposed to, say, a C function)
• Static methods and classes
• Destructor/finalizer
• Inheritance
• Encapsulation
• Multiple inheritance (and give an example)
• Abstract class
• Interface/protocol (and different from abstract class)
• Method overriding
• Method overloading (and difference from overriding)
• Polymorphism (without resorting to examples)
• Method visibility (e.g. public/private/other)

How many ways can an argument be passed to a method. Explain each method.
