Calculer ses moyennes
Description
Mon premier programme en C, entièrement recodé. Il n'est pas vraiment révolutionnaire mais permet de calculer simplement ses moyennes (donc destiné aux étudiants) selon certains paramètres, et d'afficher les résultats dans un graphe.
On peut maintenant choisir ses propres coefficients (de 1 à 99), sauvegarder les notes, charger des tableaux de notes, on peut également afficher la médiane et l'étendue des notes. L'application permet aussi de faire un screenshot de la fenêtre (cette fonction n'est pas de moi, je l'ai trouvée ici). J'ai également rajouté une fenêtre qui affiche les coefficients pour le BAC des 3 principales filières (L, S, SES) ainsi que leurs spécialités. Pourquoi ? Cela m'a permis de gérer une TreeView.
(J'ai utilisé win32 donc le programme tourne uniquement sous Windows)
Développé sous Codes::Blocks (final: 74ko).
Je compte l'intégrer à une "suite" de logiciels de bureautique pour étudiants.
Au passage, si quelqu'un a des idées d'applications à proposer...
