Yeah, Bill Amend does that kind of thing.
Not sure why he uses "int main(void)", though.

Yes, well, you understand memory things (that's what the asterisk is for, correct?). I don't. Hence I leave it blank and stuff.
For console window-based programs, that works just fine, and OpenGL doesn't even LIKE using that in a program, so...

Man, that comic is old. Make sure you guys get the patch to bring it up to version 1.0.1.
There are two legal ways to define the main() function in C:
int main(void) - ignoring command-line arguments
int main(int argc, char *argv[]) - argc is number of command line arguments (counting the program name, which is argv[0]), argv is an array of the arguments themselves
The default return value is int, so these are identical:
int main(void)
main(void)
The default parameter list is void, so these are identical:
int main(void)
int main()
main()
I prefer to write (void) instead of () because although they're identical in a function definition, in a function declaration, () means something different. In particular,
int dosomestuff();
and
int dosomestuff(void);
might seem to be identical, but the first one actually tells the compiler not to check the parameters. That is, if you later call
dosomestuff(i, j, "!@#");
it won't be able to diagnose that you gave the function three arguments it doesn't need. With the second declaration of dosomestuff, it can tell you exactly where you messed up.
