Ce programme simule le fonctionnement d’une calculatrice simple. Il permet de réaliser les quatre opérations de base que sont l’addition, la soustraction, la multiplication et la division. Destiné à des élèves de l’école primaire, il utilise les symboles +, -, x et : pour réaliser respectivement l’addition, la soustraction, la multiplication et la division. Il ne réalise en outre que les divisions entières et affiche le reste de ces divisions si nécessaire. Il vérifie bien évidemment que, dans le cas d’une division, le dénominateur n’est pas 0. Usage : perl calculatrice.pl <nombre1> <signe> <nombre2>
