Why bother converting between 'FILE *' and 'int'??
Because it is easier to use fopen for a beginner. open requires flags and mode settings.
does partial write need be considered??
That is what len does. It remembers how many bytes the read call got, for the write call.
the K&R code which seems to confuse people:
-- usage: ./copy < infile > outfile
That simple enough?
This is shell programming assignment.

DRRACKET(1) General Commands Manual DRRACKET(1)NAME
drracket - the Racket programming environment
SYNOPSIS
drracket [ Xoption ... ] [ file ... ]
DESCRIPTION
DrRacket is the Racket programming environment.
The drracket program treats non-switch command-line arguments as files to open.
X OPTIONS
When running in X11, DrRacket accepts the following standard Xoptions: -display disp, -geometry geom, -bg color, -background color, -fg
color, -foreground color, -fn font, -font font, -iconic, -name name, -rv, -reverse, +rv, -selectionTimeout time, -synchronous, -title name,
-xnllanguage lang, -xrm file.
In addition, the option -singleInstance is treated like an X option (it must appear before all other options), and it runs DrRacket in sin-
gle-instance mode. In single-instance mode, when an existing instance is running with the same host and executable name, all non-option
arguments are treated as file names and sent to the existing instance.
