On the command line gcc asia.c?
Because that would be very unfortunate. In C all functions come from
expernal libraries and printf is in stdio.h
man 3 printf
and see. 3 is needed because we want the c library and not the
commandline program of the same name.

this is all about processes. INTO the program goes argc and argv and
OUT comes an integer. argv and argc are arguments that are command line
options.
like if you do a
myprog.exe 'not pretty print'
then the single arg 'not pretty print' goes into argv[1] (argv[0] is the
program name) and argc is is the number of command line arguments.
Your school is in a rush to get you through their program. I'm trying
to make a programmer out of you.
