FOUNDATIONS OF COMPUTER SCIENCE - channel 2

The objective of the course is to give the students an overview of the information science by introducing the methodologies and the technologies used in the automatic processing of data.

Basic programming concepts by using the ANSI C programming language will be provided, together with fundamentals data structures and algorithms.

Moreover, through a wide experimentation also in some lab sessions, students will learn how to solve problems by developing correct, efficient and well-structured programs.
