Learning objectives
The objective of the course is to provide the student with the ability to understand the principles of computer science and programming using C as the reference language and in particular:
* Data representation
* Algorithm concept
* Basic architecture of processing systems
* Procedural programming paradigm
* Introduction to software engineering
The skills to apply the knowledge listed concern the development of the so-called "computational thinking":
* Decomposition of complex problems
* Top-Down problem solving
* Syntax and semantics of the C language
Prerequisites
No propaedeutics. However, it is assumed that the student knows the basics of using computers and the Internet - the equivalent of modules 1, 2, 3 and 7 of the ECDL (European Computer Driving Licence) syllabus.

Teaching methods
Classroom lessons, with the help of slides made available to students in advance. Guided solution of classroom exercises. Programming exercises in the laboratory.
Laboratory exercises are the most critical part of the course. The proposed exercises are relayed to the same general topics as the classroom lessons. The idea is to introduce the principles of programming, guiding the student to the solution of problems with an increasing level of complexity.
Assessment methods and criteria
Programming test, using C, in two hours in the laboratory
