Bridging Courses

There are no mandatory prerequisites.

It is recommended to take the exam of Procedural Programming after taking the exam of Logic, Algebra and Geometry and before taking all the other exams of informatics.

Learning Achievements (Dublin Descriptors)

Knowledge and understanding
The student will acquire the fundamental knowledge in the field of computer programming, especially for the procedural imperative programming paradigm exemplified through the ANSI C language, and will become familiar with the terminology for constant definitions, variable declarations, arithmetical-logical expressions, programming statements, functions, parameters, libraries, and data types. Moreover, the student will know a methodology for developing small-size software systems, as well as the technique of Hoare triples for verifying their correctness.

Applying knowledge and understanding
The student will be able to design and develop small-size software systems by means of the application of a methodology that covers problem analysis, algorithm design, and program implementation, testing, verification, and maintenance. As far as the implementation phase is concerned, the student will know to carry it out through a procedural imperative programming language.

Making judgements
The student will be able to evaluate and compare alternative designs of the same small-size software system, as well as to analyze and contrast alternative implementations of the same software design.

Communication skills
The student will be able to appropriately use the terminology of procedural imperative programming languages. Furthermore, the student will know to illustrate the main characteristics of the design and the implementation of a small-size software system, including the production of the software system documentation in terms of technical report, internal comments, and user manual.

Learning skills
The student will acquire the capacity of learning the syntactical and semantical features of any procedural imperative programming language.

Assessment

Project, written exam, and oral exam.

The project, which changes at each exam session, consists of implementing an ANSI C program or library by following the methodology for developing software "in the small" presented during the course. It has to be submitted at least 10 days before the written exam. In case of late submission, a 3/30 penalty is applied for each day after the deadline.  Should the project be resubmitted in a subsequent exam call, the mark of the previously submitted project is canceled; if the resubmission takes place in the same exam session, a 4/30 penalty is applied to the mark of the newly submitted project because the developers can benefit from the correction of the previously submitted project. The project is passed if the mark is at least 18/30; the mark is valid until the third exam session after the one in which the project is submitted.

The written exam, which changes at each exam call and can be taken only if the project has been passed, consists of 8 questions plus 2 exercises to carry out in 90 minutes. It is passed if the mark is at least 18/30; the mark is valid only for the exam call in which the written exam is taken.

The oral exam, which can be taken only if the project and the written exam have been passed, consists of a discussion of the project and of the written exam, plus further questions. If passed, it determines an adjustment between -5/30 and 5/30 of the average of the two previous marks, thus yielding the final mark.
