CALCULER SES MOYENNES

Voila mon premier programme en C (je n'avais jamais touché à ce langage avant), 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.
Ce que je trouve assez sympa, c'est qu'il ne prend que 46Ko (ce qui est moins que le bloc note de 69Ko).

(Attention, j'ai utilisé win32 donc le programme tourne uniquement sous Windows)
