Educational objectives

Understanding the concepts of object-oriented programming and events.
Ability to build applications.
Ability to compare possible solutions to choose the best.
Ability to apply patterns of classical solutions to new problems.
Ability to design the hierarchy of objects suitable to the specific problem.
Ability to implement programs of professional interfaces.

Prerequisites

It is useful to have taken the exam of Procedural programming.

In particular it is important to be familiar with the following concepts: pointers, dynamic memory management, elementary algorithms.

Teaching methods

Lectures, laboratory exercises.

Learning verification modality

Written and oral exam. Tests of exoneration are planned during the course.
The written exam involves the solution of three exercises and is designed to test the ability to correctly apply the theoretical knowledge and understanding of the issues proposed.
The written exam lasts three hours.

The oral exam is a discussion lasting about 30 minutes designed to ascertain the level of knowledge and understanding about the theoretical contents of the course reached by the student. Also the oral exam will test the ability of communication of the student and the ability of autonomous organization of the speech.
At the request of the student the exam may be taken also in English.
