man sscanf:
<description of type specifiers>
       n      Nothing  is expected; instead, the number of characters consumed
              thus far from the input is  stored  through  the  next  pointer,
              which  must  be  a  pointer  to  int.  This is not a conversion,
              although it can be suppressed with the *  assignment-suppression
              character.

Which is why it is always 0 (no characters had been consumed).
It should be sscanf("%d",&n);
