This is driving me nuts.
I'm writing a password program that reads from .txt file into an array of char arrays, and then allows the user to write a new password and then appends it to the end of the list.
Everything SEEMS to be working except everytime I run the program with existing passwords in the the .txt file and then save it, it adds a newline.
Here's my program minuys the functions that don't touch fstream or the lastIndex (my counter for existing passwords) - the problem seems to be in the initialization, new entry or write functions. I can't pin it down and have no clue why its doing this. Can someone please help me, I feel like my brain is gonna explode
