Delete files from a directory

This program will permanently delete all files from a working directory. This program is aimed at beginners so that they can get to know how to use the kill statement, something I learnt recently myself. This program removes all files from a working directory on a computer, but leaves folders intact if there are any contained within the directory itself. This is something I am working on to improve. If you have any comments on this submission, please do leave them since I'd love to hear what you have to say and do vote if you like the program.
