Need help with this assignment, I will provide a code that I found on here but when ran, it would not open the file I needed it to$.$ In my file explorer it's called "sequence" but when opened in my IDE DevC$++$ it's named "sequence.txt$"$ so I cant even tell if it works or not, If on windows the sequence doc is just values listed in notepad, first number is how many numbers are in the sequence followed by said amount of numbers. Ex:

$2$

$5$

$6$

assignment details in picuture, PLEASE provide whole code to copy even if you did minor changes. Also There is no comment section and others can't seem to find one either, so is there another way to contact you to help with further details on this code? Since i dont want to leave a thumbs up on a code that I cant get to run, or leave a thumbs down when I pretty sure the fix could be something simple:
