Answer 1

What error? How to reproduce it?

Here's my input:
Igor
D
12
E

I see your input must contain as least 4 lines in the following order:
Name
Option
Amount
Exit

If something is ommited there will be an error.

Answer 2

Your code don't have any synthetic errors i guess you facing issues in input data . In solo you need to give all the inputs at run time try it this will work fine .
