Lab Work – A Guided Tour of Programming

Download final program (outcome) demo (only for Windows 64-bit).

In the lab sessions, you will learn the concepts of programming through a series of guided exercises. You are required to work in pairs, i.e. two students on one computer.

The programming tour starts by assuming you have zero programming knowledge.

Please prepare a USB flash drive for the use in the lab sessions. You should do the preparation work as described in the slides before the first lab session.
