Création de classe "vector"
Bonjour, je souhaite créer une classe "vector" pour la programmation d'un arduino. En effet, je n'ai pas pu inclure dans mon projet les fichiers STL qui me permette d'utiliser cette classe. J'ai quelques erreurs dans mon code et je voudrais de l'aide pour les corriger. Merci

void pop_back();
int getSize();
