I should clarify, the main purpose of the challenge is to loop over files. Printing the file names is just a silly example of a use case for looping over files. Therefore, it doesn't matter whether the file name is prefixed with "./test/" or not; adding or removing the prefix is easy enough to do. Also, relying on "ls" to print all the file names is invalid, because that just outsources the loop to C; we're interested in having a shell script which can iterate over all the files in a directory and do something useful with the file names.

I've updated the original post to clarify.
