Hello! I have written written my own class, which includes a header file and a .cpp file. I have also written the driver for this program. Everything looks fine to me, but I am receiving about 20 random errors. I will post my code for all 3 files but I believe it is a problem that can be diagnosed using just the driver.
The program is a bank account program that adds new accounts, withdraws, deposits, updates, displays, etc. Any help would be greatly appreciated! Thanks.
