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.

I have a few suggestions:
ntttt
is everywhere, move it into a function which takes and returns a string, and prepends whatever string it is given with this format - the benefit of this is that if you change your formatting in the future, you only need to do it in one place.- Getting the user to enter their ID is a common operation, so put this logic all in one place. i.e.
std::cout << "ntttt--> Please enter your ID: ";
getInput(id);
account = findAccount(id);
Should be lopped out into its own function, again for the same reason - if the way you want to do it changes, you only need to do it in one place! - Move the code within each case block into its own function, e.g for
case 2
, just make a function calledcheckBalance
which does exactly that. Call it from the case block (similar to how you have done forcase 1
). The comments already hint at what each block does, but the whole of the switch/case statement is quite a lot of code! - The way you look up accounts is a little confusing and potentially inefficient for large numbers of accounts, I would use a map (http://www.cplusplus.com/reference/map/map/) with the key being the ID.
I hope this is enough to get you on your way, if you give this another stab then I'm happy to take another look!
