}Ok so I have this code. The code reads a text file, stores the information into an array then displays the contents on the screen when I run the code. So basically what I have is a .txt file with a list of users e.g:
username, password
matt, 123
What I want the code to do is allow me to enter new users into that text file. I have browsed through the i-net and it seems that the .txt file cannot be just edited. The information has to be stored into an array, and then the extra information I wish to add be added to that array, then the array printed into a new .txt file. How exactly can I modify the code to do this? Any help is appreciated. Thanks
