    What is the significance of using a char porinter in #define any_size(any) (char*)(&any)-(char*)((&any)-1) ?Why can't we use any other pointer there?

    A generic method for doing this would betypedef int MyType;MyType *p = 0;return (int) ++p;of course, the ++ operator uses sizeof itself, but this is still a valid answer to an interview question in my opinion.
