/* "r": lecture seule. Vous pourrez lire le contenu du fichier, mais pas y écrire. Le fichier doit avoir été créé au préalable. "w": écriture seule. Vous pourrez écrire dans le fichier, mais pas lire son contenu. Si le fichier n'existe pas, il sera créé. "a": mode d'ajout. Vous écrirez dans le fichier, en partant de la fin du fichier. Vous ajouterez donc du texte à la fin du fichier. Si le fichier n'existe pas, il sera créé. "r+": lecture et écriture. Vous pourrez lire et écrire dans le fichier. Le fichier doit avoir été créé au préalable. "w+": lecture et écriture, avec suppression du contenu au préalable. Le fichier est donc d'abord vidé de son contenu, vous pouvez y écrire, et le lire ensuite. Si le fichier n'existe pas, il sera créé. "a+": ajout en lecture / écriture à la fin. Vous écrivez et lisez du texte à partir de la fin du fichier. Si le fichier n'existe pas, il sera créé. */ // Exemple int main(int argc, char *argv[]) { FILE* fichier = NULL; fichier = fopen("test.txt", "r+"); return 0; }
