how can I invoke a process with a single argument
on the command line representing a number?
I mean,   the filename of the program is "game.c"
how can I input "game 1234"  to invoke this program
instead of inputting:
game
1234

Thanks!

and it you want to execute it from your prog use the command execl(...)
