Sending an email of the results from 1 Class to another
Alright so I have written this dice wagering game where we use classes that store a bank account balacne class for die rolling and a class that send an email of the results/when they are out of money. My issue seems to be when I try to call the SMTP method into the Driver program I am given an error no matter what I do.
