process of converting/presenting source code in a legible/attractive way
Use of Object-Oriented Techniques
What is instantiation/initialisation?
Instantiation = Initialisation
Creation of an object
Use of Object-Oriented Techniques
What is polymorphism?
A method in a child class overwriting parent class methods
Use of Object-Oriented Techniques
What is encapsulation?
The use of different techniques (e.g. privating attributes) to ensure that data can only be accessed within a class
What is the difference between global variables and local variables?
Global variables can be accessed from anywhere in the program
Local variables can only be accessed within their module
Use of Object-Oriented Techniques
What is a class?
A template for the methods and attributes of an object
Use of Object-Oriented Techniques
What is an attribute?

Use of Object-Oriented Techniques

Subroutines and Recursion
What is the difference between passing a parameter by value and by reference?

* treated as local variable - original will not be affected
