CSI221 -Introduction to Data Structures
Written by: Max Baird, course lecturer

Course Description

The course will introduce students to the design of algorithms and the analysis of their efficiency in terms of time consumption, storage requirements and code complexity. Algorithms for a variety of purposes will be considered, concentrating on those for performing operations on data sets such as searching and sorting. Data structures that support these operations will be discussed, along with common applications of their practical use in primary and secondary storage.
The C programming language will be used for the course. The course will help students to improve their C programming skills. Some new programming techniques will be introduced and good programming practice applicable to any language will be emphasized throughout the course.
