You are incrementing the _address_ that argv[0] points to by one and
then casting the address to an integer.
Casting doesn't work like what you seem to expect to want it to do.
Take a look at the atoi() function. Try: atoi(argv[0]) + 1
(Although, I doubt that will work since the first argument is usually
the command that initiated the executable. You probably want argv[1]).
