This is C$++$ program that I am running in with a lot of issues.

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.

$-$ 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.
