Problème c# Fermé

Question

Bonjour, 
J'ai un exercice à faire. C'est une sorte de questionnaire de quatres questions à choix multiples. L'utilisateur doit entrer son choix de réponse ( a,b,c,d,e) pour chaque question. Si il entre la bonne réponse, on affiche Bravo, sinon on affiche Attention. À la fin, on calcule le nombre de bonnes réponses et on affiche un message "Le cumulatif est de 75%" si il entre 3 bonnes réponses (chaque réponse vaut 15%). Comment faire pour l'accumulatif ? Je sais pas, merci pour votre aide

Bonjour l'aide pas message privé est interdite par la charte.
Le but du forum est l'entraide transparente et la pédagogie.

Ce qui implique aussi que l'on ne donne pas le résultat d'un exercice, mais des pistes pour y arriver.

Bonjour,

Je ne connaissais donc pas cette partie de la charte!

Pour ce qui est du problèmes qui nous concerne :

Je t'ai déjà donné la solution en entier et je pense que tu est en mesure de trouvé la solution à partir du code que je t'ai donné.

Il suffit simplement de déclarer une variable à 0 et d'incrémenter cette valeur de 25 pour chaque bonne réponse pour obtenir une note sur 100.

L'opérateur d'incrémentation en C# es le suivant +=
