Implémentation d'une matrice décroissante
Depuis l'aube des ordinateurs, Hollywood a grandement démontré qu'un pirate informatique ou un programmeur était quelqu'un assis sur un ordinateur, tapant des touches aléatoires sur un ordinateur qui finit par se compiler en une simulation de type matrice tombante. Ici, nous allons essayer d'implémenter une simulation de matrice descendante similaire sur la console en utilisant C++.
L'idée ici est d'imprimer des caractères aléatoires sur une largeur définie où les deux caractères successifs peuvent ou non avoir un certain espace défini de manière aléatoire. Un certain délai entre l'impression des lignes successives doit être mis en œuvre afin d'avoir un « effet descendant ».
