command line arguments in C programming

digitalranadigitalrana Posts: 19Member
hi...im a new programmer in C and we have this assignment to do...i'v managed most of it but one of the specifications is that if the user enters "-gnuplot" after the program name in the command line, the program should pass its values to gnuplot and use gnuplot to graph the results of the program...that's what i understand from it...does anybody know how i can pass the results i've obtained to gnuplot?

here's the actual question for that part:
f)If -gnuplot is specified, the output is being pipe to the gnuplot
program and hence will need to have gnuplot commands prepended
and appended.
% a.out -gnuplot |gnuplot
You will need to find out how to use gnuplot from
http://www.gnuplot.info/documentation.html

Thanks in advance.
