You're right about argv[1] being the value of the
first parameter and you can use that together with
argc for the number of parameters. So a simple little
loop like:
for(i=1;i<=argc;i++) {
do stuff with argv[i]
}
would process each parameter in order.
For the second example, you're processing the
filenames from stdin. You simply treat stdin just
like a file and read the "file" to obtain the "data"
