I am having problems with some of the cases listed bellow code...any help you be great. for example I am having problems with number 4....but really I am having problems with all of them...

Some test cases that you may want to consider include the following:

1. What if one of the files contains no numbers?
2. What if both of the files contain no numbers?
3. What happens if one of the files has many more numbers than the other?
4. What happens if there are several blank lines after the last number in both files?
5. What happens if there are no blank lines, spaces, or characters of any sort after the last number in each file?

All these would be fixed if you apply the method i suggested in your other post.
