I read it to mean we needed to get a list of all executable files in each of the directories listed in the path, and any name that appeared in more than one directory were regarded as suspicious and the full path of each "copy" printed. I also underst...

I am having an issue where isalphanum() is allowing some characters through that when I print to stdout they appear as a black diamond with a white question mark. (WSL ubuntu bash) locale command comes back with LANG C.UTF-8 LANGUAGE LC CTYPE "C.UTF-8"...

I didn't partner up for this project, my schedule wasn't suitable, but in the java unit my partner and I had a similar level of knowledge. We both worked individually on our project, but 2 or 3 times each week we had a microsoft teams meeting where...

Maybe you are making system calls that are not portable? Or using POSIX headers? I would have assumed that the program would fail to compile in that case, but not certain. Either way the project won't be tested on windows.

I think what you are asking is how to get the ascii value of a symbol character. That would be typecasting char c; int x; x (int)(c); I think you are probably trying to check if a crontab "word" is an asterisk. I think there are easier ways than what yo...

Yes, 20 commands at most. It could contain ten commands but 20 non comment lines for example, if each command had two different times to run

(politely) it is not obvious if this is contradictory. It could mean run only when the day of the month matches the day of the week in a given month, (which would be kind of obtuse imo), or it could mean run on every monday and run on every 13th of th...

By "the data itself" this includes that if it specifies the day of the month as a date, that there are enough days in the month (not worrying about leap years)? what is the behaviour if a day of the month and a day of the week is specified? does that...

For the requirement to check for errors in the crontab-file and the estimate-file, are we guaranteed that "The crontab-file and the estimates-file will each contain at most 20 non-comment lines. Each line will be at most 100 characters long, and each ...

Also, if the reason you want to transfer stuff from windows to wsl linux is to get something you downloaded into wsl, say a code example like https teaching.csse.uwa.edu.au units CITS2002 labsheets square.c, you can use the command "wget". For exampl...
