Answer 2

If you look at a classic C string like char str[] = {"Hello"}, "str" is a pointer to the first element of the char array and you can move the pointer to the next char by adding 1. *(str+1) points to the second character, 'e'. It's equivalent to str[1]. Same with *(str+2) = str[2] etc. Hence the first element is str[0] which is equivalent to *(str+0) (or simply *str). If you think about it, it would be highly confusing if array indices started with 1. You'd always have to consider that str[n] means something else than *(str+n).
