Answer 1

I am writing this answer with the hopes that it may help someone else out there that wants a very simple solution to this problem.

In my case the problem was due to some files having different line endings such as '\r' vs. '\n'. Everything worked fine in windows but then it failed in Linux.

The answer was actually simple. I created a function removeNewLineChar after each line was read in. That way the char was removed. The removeNewLineChar takes in the line that was read in and copies it over character by character into a new string but it avoids copying either of the newline characters.

Here is a full explanation of how that works.
