Thread: CS2 Assignment: Error

In CS2 we had to write a basic bank program with classes. I wrote the program, in a well done manner imo, but the output is messed up. Me and my teacher both must be missing the problem, as we have tried several things to no avail. I know its gotta be something lame, the output is commented at the end of the program, its not commented but should be pretty easy to follow.
