1 Introduction
Dear student

As noted in tutorial letter 101, this is a blended module, and therefore much of your module is available
on myUnisa. However, in order to support you in your learning process, we also provide this study
material in printed format.

Below you will find all the material that is available on the COS3711 site on myUnisa.

COS3711 - Advanced Programming

Welcome to COS3711 – a module on advanced programming concepts – from your lecturer, Mr Colin
Pilkington.

Major concepts

The major concepts you will learn include:
 Using libraries
 Understanding and implementing design patterns (there are many design patterns,
and you will focus on only a few this year)
 XML parsing
 Validating input
 Reflective programming
 Concurrency using threads and processes
 Network programming
 Cloud computing

Assumed background knowledge

It is assumed that you are proficient in the following skills (which you should have gained in your
previous studies):
 C++: creating classes and objects, inheritance and polymorphism, pointers, templates, reading
from and writing to files, .h and .cpp file usage, and the use of public/protected/private
 Qt: console and GUI applications, signals and slots, Qt container classes
 Understanding UML diagrams
 Design patterns: understanding of some design patterns such as Composite, Observer,
Serializer, Flyweight, Monostate, and Command

Assessment

You will be assessed in various ways in this module. The 2 assignments are practical assignments, and
you will have to design, code, compile, and run applications in preparation for submission. The exam,
however, is a written exam (with no practical component), and you will be expected to understand the
theory behind what you are doing, as well as writing code to implement concepts.

You will continue using the Qt framework that was used in COS2614.

We trust that you will enjoy this semester as you extend your C++ skills.

Your responsibility

A quick note about your responsibility as a student: you need to work through the prescribed textbook,
tutorial letters and lesson units, do all the exercises, and also do all the assignments – both the parts that
are submitted for marking and the self-assessment parts. This will not guarantee success, but without it,
it will be very difficult to pass.
