Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

This course covers the following material: Concepts of computer, algorithm, program. Basic notions of algorithmics. Introduction to C language programming. Time and space complexity, "big-O" notation. Correctness and termination anaysis of programs. Functions and procedures, recursion. Manipulation of arrays and character strings. Structures, pointers, dynamic memory allocation. Elementary data structures: stacks and queues.

Learning outcomes of the learning unit

At the end of this course, students will be able to develop algorithms for solving simple problems, as well as to analyze their correctness, termination, and performance. They will master the basics of the C language, and will be able to program their solutions in this language.

This course contributes to the learning outcomes I.1, I.2, II.1, III.1, III.2 of the BSc in engineering.

Prerequisite knowledge and skills

There is no prerequisite.

Planned learning activities and teaching methods

  • Theoretical lectures.
  • Exercise sessions aimed at making students understand the theory, and become able to apply it to concrete problems. The tools that make it possible for students to program their solutions on their own computer will be explained in the course of these exercise sessions.

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face course

Additional information:

  • Theoretical lectures are given by the professor.
  • Exercise sessions are supervised by an assistant, helped by student teaching aids. These sessions are held in groups of about forty students.

Recommended or required readings

Course notes are published by the student union press (CdC). A copy of he slides used during the lessons can also be downloaded from the course webpage. Students looking for a reference document on the C language can read The C Programming Language (2nd edition), Brian W. Kernighan, Dennis M. Ritchie, or its french translation. (It is not mandatory to buy this book in order to follow the course.)


Exam(s) in session

Any session

- In-person

written exam ( open-ended questions )

Additional information:

A written exam (open questions) in January, June (for first-block students), and September. This exam will be held either at the university or remotely, depending on the sanitary situation.
