What is the correct declaration of main?

There are two valid declarations:

int main(void)

int main(int argc, char **argv)

although they can be written in a variety of ways. The second parameter may be declared
char *argv[] , you can use any names for the two parameters, and you can use old-style

int main()

int main(argc, argv)

int argc; char **argv;
