I am having probs in the addApt function where I am using the push_back function to add another vector. when I run the prog and add an apt, it doesn't actually add the apt even though the "success" statement has shown from my apartment constructor. I think it might have something to do with having the constructor in the parameter for the push_back function but I am unsure. thanks for your help!!!
