Note that I have placed all the data files in a sub
directory (or sub folder) called data. In unix we use the "/"
to specify directories on the path to your file. In windows, we use
the "
" to specify directories on the path to your
file. This very small difference has caused many software engineers
much pain in trying to write portable programs that run well on both
unix and windows systems. I am using Linux an open source version of
unix
