A.Y. 2024/2025
Learning objectives
The course aims at introducing basics of Computer Science, with a particular emphasis on Programming. Basic concepts on the digital representation of information and on computer architetture are outlined. The notions of algorithm and program are presented, as long as main tools involved in software design. Structured programming and the imperative paradigm are settled, focusing on modular software design. Some relevant data strutture and algorithms are presente, addressing the evaluation of algorithmic time complexity.
Expected learning outcomes
The student will be able to:
1) Approach problems typically dealing with data analysis, and conceptually design solution algorithms.
2) Code modular algorithms by choosing appropriate data structure and constructions offered by the selected programming language.
3) Manage an operating system to code, compile, link and execute programs.

Assessment methods and Criteria
The exam consists of a written exam plus a lab exam:
- In the written exam, some programming exercises are proposed, particularly aiming at checking the knowledge of the theoretical bases of programming and the ability of designing simple algorithms. The time allowed for the written exam is two hours, during which students are not enabled to consult any reference. In the evaluation of this written exam, rating from 1 to 30, both the ability of conceptually projecting algorithms and the correctness of the formal specification of such algorithms in the chosen programming language is taken under consideration.
- In the lab exam, a data analysis project of a certain complexity is proposed, for which the production of working and well structured software is required. The time allowed for the lab exam is about three hours, during which students are enabled to use their software developed during lab lectures. In the evaluation of this lab exam, rating from 1 to 30, the ability of projecting algorithms as well as producing modular, well structured and maintainable code is taken under consideration.
The final evaluation, rating from 1 to 30, earned by the student for this course originates by suitably averaging the evaluation of both the written and the lab exam. An evaluation between 18 and 23 indicates an appropriate level of knowledge of theoretical and practical basics of computer science and programming, an evaluation between 24 and 27 indicates a good knowledge of such basics, higher evaluations indicate a very good knowledge and originality in applying basics in computer science and programming.

Assessment methods and Criteria
The exam consists of a written test and a laboratory test. Each test is evaluated independently and in the case of a positive evaluation (greater than or equal to 18) of both tests, the two marks contribute to forming the final mark, given by the arithmetic average of the two marks, rounded up to the next integer.
The written test takes place without the use of texts and /or notes and focuses on the fundamental conceptual rules of C ++ and on the development of the simple algorithms.
The laboratory test involves the development of C ++ algorithms relating to topics explicitly covered in the course and /or in the courses carried out in parallel (analysis, mechanics and statistics), during the test the student can consult bibliographic material and personal folder which he completed during the laboratory sessions (and completed independently).
