yes, there will be times when your program needs to know the number of
command line arguments and what they are. When that is the case, you can
define
main differently.
int main(int argc, char *argv[ ]) {
so argc is the number of command line arguments and argv will hold the
actual command line arguments.
btw, argv[0] is always the name of the program executable itself.

I've also seen int main(void)
I believe that's just for arguments sake though, so the OS won't pass in
anything on the stack, though I'm not really sure.

The main function returns an integer to the operating system indicating the
success or failure of the program. You should code int main( ).
I've actually seen void main(void) in C textbooks, and yes it will work, but
technically it is incorrect to do so, because the operating system is
expecting an integer to be returned from your C program.
