I have been learning C++ and recently I have started practicing classes. I made this simulation of a banking system with an Account class. I would like to hear feedback on my code, what is good - what I should keep doing, and especially what I should pay more attention to, or if you have any suggestion on how to simplify parts of the code, make it more readable because I feel this could be improved. Also, I would like to hear comments on exception handling, since I am quite new to that as well. Thank you all in advance, I will do my best to implement any of your suggestions.
