int main()

[Sabal]

Hello,

Ive seen int main() written like this, int main(int argc, char *argv[]) or in this fashion a lot, and i was curious what the purpose of writing it like that is, compared to just simply writing int main().

this has just been somthing that has been on my mind a bit, and would appreciate any help as to what the difference and benefit to doing so is,

Thanks,
Sabal

If the program is called with parameters, argc saves the number of parameters and argv saves the parameters.
This was often used for DOS programms but today it's not realy usual.

I hope I could help you.
