Here's an answer to question 2 that I don't think breaks any of the rules
int dispnum ( int num, int last )
{
printf("%d\n", num);
return((num > last) ?
(num=(num < 100) ? dispnum(++num, ++last) : dispnum(num, num)) :
(num=(num > 1) ? dispnum (--num, --last) : 0 ));
}
void main()
{
dispnum(1, 0);
}
How's that? A little recursion but no (explicit) if's in there. Notice also the
judicious absence of comments :-)
Question 1 has me stumped at the moment of course question 2 may also
have me stumped and I just don't know it yet.
