It encompasses definitions, operations on words, and finite representations of languages, alongside regular expressions and finite state automata. Additionally, it includes theoretical concepts, properties, and exercises to reinforce understanding.
Ce cours est une initiation à la théorie des langages formels, qui vise à comprendre comment les langages servent de supports de communication entre les êtres humains et les machines. Les langages naturels sont informels et ambigus, tandis que les langages artificiels doivent être formalisés pour l'interprétation par les ordinateurs. Le document couvre les phases d'analyse lexicale, syntaxique et sémantique nécessaires à la communication avec les machines.
This course introduces the theory of languages through three aspects: recognition by finite automata, grammar generation, and representation by measurable properties. The objective is to extend knowledge of language theory and automata to programming language description and syntax analysis for compilation. A mini compiler project will be part of the course.
This document covers polymorphism in C++ through exercises involving class inheritance and virtual functions. Key concepts include method overriding and the behavior of virtual and non-virtual methods. It also involves hands-on coding examples to illustrate these concepts.
This document describes the development of a multi-phase project to create the game 'Vache/Taureau' in Java. The first phase focuses on building a console-based application to implement the game's core functionality: comparing player guesses with a random number and scoring based on matches. In subsequent phases, a graphical user interface and database integration for user management and scores are introduced. Game configurations, scoring rules, and multi-player support are also specified to enhance functionality and complexity throughout the development process.
This document introduces the key concepts of exception handling in Java, explaining how errors can disrupt program execution and how the 'try', 'catch', and 'finally' blocks can manage them.
