Hello!

I was just wondering whether the input file will always be called in.txt, and the outfile will always be called out.txt since the project description says that we should take in.txt and out.txt as command-line arguments.

Yes. The spec explicitly states the names of the files will be in.txt and out.txt

If a filename other than in.txt or out.txt is passed in should these be used instead? And if so, should I check that the extension is always .txt ?

As Anon said it is good practice to be able to read a file of any name as opposed to a hard coded value. However, for this project you can assume that the file name passed in as a command line argument is always correct. So, no checking is necessary.

Thank you!
