I have a notepad with the following format:
  • Column 1 - Code;
  • Column 2 - Username;
  • Column 3 - Password;
  • Column 4 - Name;
The objetive of my program is to add new users to the notepad.
So, how can I create a unique numeric code for the new user between 1 and 99 and add the new user to the list? The code must match the lowest available number in the list.
Thanks

"I have a notepad..."
No, you have a text file.
Notepad is a Microsoft text editor, i.e. it is an application that runs on a computer. A text file is a kind of computer file containing text data.
