La Programmation en C++ - Un tout premier programme : l'incontournable "Hello World!" Un tout premier programme : l'incontournable "Hello World!" Le "Hello, World!" semble être une véritable tradition dans le monde de la programmation. Je crois que je n'ai pas trouvé un seul livre sur leC/C++ qui ne commence par cet exemple, donc je vais faire de même. Les chiffres sur la gauche sont juste là pour indiquer le numéro de chaque ligne, ils ne font pas partie du programme. Vous voyez, c'est... pas si simple que ça. L'instruction principale, c'est clairement le cout << "Hello, World! On voit ensuite que cette instruction principale est enfermée dans un bloc {} (lignes 3 et 5). Notez bien que main() s'écrit avec des minuscules. Et puis il y a cette première ligne, un peu différente des autres : #include <iostream.h>. Voici les points essentiels à retenir: Afin de vous assurer d'avoir tout compris, voici quelques exercices que vous pourrez essayer: Après chaque exercice, recompilez votre programme et lancez-le pour voir les résultats (si il compile correctement).

Coroutines in C by Simon Tatham Introduction Structuring a large program is always a difficult job. One of the particular problems that often comes up is this: if you have a piece of code producing data, and another piece of code consuming it, which should be the caller and which should be the callee? Here is a very simple piece of run-length decompression code, and an equally simple piece of parser code: Each of these code fragments is very simple, and easy to read and understand. In many modern operating systems, you could do this using pipes between two processes or two threads. emit() in the decompressor writes to a pipe, and getchar() in the parser reads from the other end of the same pipe. In this article I offer a creative solution to this sort of structure problem. Rewriting The conventional answer is to rewrite one of the ends of the communication channel so that it's a function that can be called. Of course you don't have to rewrite both of them; just one will do. And that's the point, really.

learn programming cpp:meta_prog [Jean-Paul Rigault] Nouveautés Présentation Ce cours donne quelques compléments sur une utilisation avancée de C++, utilisant en particulier la bibliothèque Boost et le techniques de méta-programmation par “templates”. Pour une motivation et une introduction rapide à ces techniques, voir l'annonce du cours. Ce cours est aussi une introduction à quelques unes des extensions les plus importantes de la norme C++ 2011. Organisation du cours Le cours a lieu en général le mardi après-midi, à raison de 4 heures par semaine : 6 séances (plus une) au total. Ce module est constitué d'une alternance de cours et de travaux pratiques. Environnement de développement Le cours a lieu sous Linux exclusivement. Vous êtes libre de choisir votre environnement de développement favori (Emacs, Eclipse, KDevelop, Code::Blocks, etc.) du moment que vous avez appris à l'utiliser. Installation de gcc-4.8.1 sous Ubuntu 12.04 Suivez les instructions de cette page Web qui sont très simples et très claires. Documents et ressources diverses
