This is C$++$ pgogram that I am running in with a lot of issues. Would you be able to clean up anything unneeded or change anything to be more effiecient for the end goal.

So it suppoce to be a file comparison program. File$1$ has a lot of text that is located on one line only. File$2$ has the same text but is on many lines. This program should compare two of these files. If the program runs into a diffrence it gives the option to skip a certain amount of characters. So the program countinues to compare from the same character in the files $($Done because The issues in each file could be diffrent lengths.$).$ Also it prints the issues to display where the issue is present.

Issues known in the program.

$-$ There seems to be an issue with the amount of characters procecced giving not an exactly correct amount the longer the text

$-$ biggest issue is that when program file$2$ runs in to the end of line $1$ it does not get the text from line $2$ to countinue comparing and ends the program.

Can the issue be fixed since I cant get it to run the way I want. Thank you.
