Subject fundamentals
This course, mandatory for all the students, has a twofold objective: on one hand, to introduce to the student to the issues related to computer science in particular from the "cultural" standpoint, but also from the technological one. On the other hand, the course aims at teaching the use of computer programming as a way to solve realistic problems.
Expected learning outcomes
The student must acquire two fundamental types of knowledge; the solution of concrete problems through programs implemented using a programming language and to be executed on a computer; the understanding of the quantitative aspects of computer science such as performance, computational power, representation of information, computer architecture. These skills will be applied to the solution of practical problems.
Prerequisites / Assumed knowledge
No special prerequisites are expected for the course. Some basic notions of Calculus (e.g., the concept of function) and a minimal level of familiarity with the interaction with a computer.
Contents
REPRESENTATIONS OF NUMERICAL DATA (4 HRS)
-Unsigned Numbers
-Representation intervals
-Operations with pure binary numbers: Addition, Subtraction, Overflow.
-Signed Numbers (sign and magnitude and two's complement representations)
-Real Numbers (Fixed and Floating Point)
- Representation error in computers
- Fixed and Floating point representations

REPRESENTATIONS OF NON-NUMERICAL DATA (2 HRS)

-Characters encoding (ASCII, UNICODE)
- Examples of representations of other non-numerical data

BOOLEAN ALGEBRA (2 HRS]
-AND, OR, NOT operators and Boolean expressions
- truth tables of a generic Boolean expression

COMPUTER ARCHITECTURE (6 HRS)
-Von Neumann model (Program Memory, Control Unit, Operating Unit)
-CPU (execution speed) and cache
-PC architecture (devices and buses)
-Hardware and programs: assembly languages vs. high level languages

SOFTWARE ARCHITECTURE [2 HRS]
- Types of programming languages: machine language, assembly, high-level languages
-Translating high-level languages into binary code: compilers
- The operating system

PROBLEM SOLVING AND ALGORITHMS (4 HRS)
-Flow charts, pseudo-code
-Problem solving and program writing

C LANGUAGE [40 HRS]
-Data types and symbolic constants.
-Input/output operations (printf and scanf).
-Control-Flow structures (iterative and conditional).
-Arrays and multidimensional arrays (of integers, reals and characters).
-Addresses and pointers
-Functions and calls (by reference, by value, pointers).
-Strings.
-Command line arguments (argc and argv).
-Files.
-Struct.
- concept of dynamic memory
Delivery modes
The course includes about 20 hours of lab, in which the topics coverd in the classes will be implemented as C programs.
Texts, readings, handouts and other learning resources
- Handouts of class material.
- H.M.Deitel e P.J.Deitel, "C: How to Program", 6th edition, Prentice-Hall titolare dell’insegnamento.
The textbooks, chosen among the ones listed above, will be announced in class by the instructor.
Assessment and grading criteria
The exam consists of a written test that aims at assessing the students’ knowledge of the theoretical aspects of the course (through numerical exercises or open-answer questions) and the programming skills (through the writing on paper of a C program that implements the solution of a practical problem). The duration of the written test is 2 hours and it is a closed book test.
The maximum score for the written test is 30 cum laude.
During the discussion of the score written test, a supplementary oral test can be requested at the discretion of the instructor or of the student, but only if the score of the written test is at least 18/30. The oral test covers the whole course program and is meant to assess and elaborate the student's skills.
Notes

Classes feature slide presentations. The classroom must allow the simultaneous use of the board and of the screen.
