Topics

Linked Lists

• Linked lists as an ADT (implementation using classes)

Unit testing

• We’ll go over some important guidelines related to unit testing

• I suggest also reading this blog post about the best (and worst) practices for unittesting your code

Makefiles and unit testing

• We will split our implementation of linked list into three files - header file (contains only the class definition), source file (contains the implementation of the class methods - no main), test file - uses the ADT. (More practice on this in lab02)
• Write a simple Makefile to compile all the different programs written in class

Non member functions and friend functions

• If a non-member function is declared to be a friend of a class, it can access the private members of the class.
• Discuss when/why you might use friend functions

Operator overloading - Pages 63 - 80 in the book

We will overload some of the operators for the Quadratic and Linked List classes.

Example from reading:

point p1, p2;
if (p1 == p2){
  cout<<"Points are equal\n";
}

We will specifically discuss:

1. Overloading binary comparison operators e.g. ==
2. Overloading binary arithmetic operators e.g. +
3. Overloading output and input operators e.g. » and «
