What This Course Is About (Software Quality Viewpoint)

A software project’s stakeholders

Course Introduction : What This Course is About — Two Viewpoints 4 / 22

What is Software Quality?

“YouRHere”Small SA company developing location-based Android apps. Three developers workingon a social, location-based, check-in application available in the Google Play store.

Identify what the projects’ stakeholders (users, development team, project sponsors)value.

Lectures/Labs/Review Sessions

Lectures:Monday, 10:15-12:00 in FNB 45 (3rd and 4th periods)Tuesday, 12:30-13:15 in FNB 47 (5th period)

Labs:Friday, 14:15-16:30 in the D-Lab (Computer Lab)

Review Sessions (you will be allocated to one session):Friday 14:15-15:15 / Friday 15:30-16:30; in WSS203/WSS204/WSS206

Laboratories

Work in groups of 2 (as for the project) in the D-Lab or elsewhereDemis are available for assistanceCount 5% (≈ 1% per lab)Formative assessment — not based on the quality/correctness of your solutions

Start this week!

Course Introduction : Course Logistics 12 / 22

Lab Assessment Procedure

To receive the mark for each lab:Work on the lab weekly and push solutions each week to GitHubSubmit completed laboratory via GitHub before the deadline (one submission pergroup)Labs will be reviewed in review sessions.

Arrive on time for the review session with your solutions and participate in discussingthe labNo late arrivals or session swapping will be permitted without prior arrangement

Forum participation: a percentage equivalent to one lab’s mark will be awardedfor participation (note, the maximum lab mark is still 5%)Achieve 65% or more in the final exam, and you will automatically be awarded 5%for the labs

Class Test, Project and Exam

Test — counts 10%1 hour written test

Project — counts 35%Done in groups of 2 (lab groups) over a number of weeksWill be a challenging problem requiring an object-oriented solution, thoroughtesting and complete documentation

Exam — counts 50%3 hour written examClosed book, basic scientific calculators allowedAll material covered in lectures, labs, readings and the course project is examinable

Recommended Textbooks

C++ Programming: From Problem Analysis to Program Design by Malik

The C++ Primer by Lippman, Moo and LajoieThe C++ Programming Language by StroustrupEffective C++ Series by MeyersC++ Coding Standards by Sutter and Alexandrescu

Additional readings/podcasts/videos will be made available

Course Introduction : C++ Resources 15 / 22

C++ Resources on the Web

Huge amount of material on the webSome of it good, some of it questionable, and a fair amount outdatedStart with the links on the course homepage, including:

Boost (peer-reviewed, portable C++ source libraries)

Course Introduction : C++ Resources 16 / 22

C++ IDEs and Compilers

The IDE (Integrated Development Environment) ̸= The CompilerOfficially supported in this course: CodeLite 12 onwards and the GCC Compiler7.3.0 - both open source, cross-platform (download from course website)Alternative Compilers:

Microsoft’s CompilerClang

Alternative IDEs:Microsoft’s Visual C++XCodeNetbeansCode::Blocks…

Important issues are: Standards, Vendors and Conformance

lecture-time)3 Split coding tasks equally (do not let your lab partner do all the coding)4 Understand when you don’t understand5 Try to keep up to date
