Re: [Dev-C++] recursion function

It would be really nice if you could give a little description of what
you thought the code was suppose to do as well as what it's really
doing.   Most importantly you are using a number of variables which
are not obvious.

What is 'c' and 'dCol'

I assume that 'sq' is a two dimensional array with 'r' and 'c' acting
as indexes but it's unclear what type the array is and what it looks
like.

After trying to decode your code:

Reference Square:
1 2 3
4 5 6
7 8 9

 if (
c> dCol &&
(
(sq[r][c - 1] != '#' && sq[r][c - 1] != ' ') ||     //  Square 4  Not
Equal to # or ' '
(sq[r + 1][c] != '#' && sq[r + 1][c] != ' ') ||   //  Square 8  Not
Equal to # or ' '
(sq[r][c + 1] != '#' && sq[r][c + 1] != ' ') ||   //  Square 6  Not
Equal to # or ' '
(sq[r - 1][c] != '#' && sq[r - 1][c] != ' ')       //  Square  2  Not
Equal to # or ' '
)
&&
        sq[r][c - 1] <= sq[r + 1][c] &&       // Square 4 <=  Square 8
        sq[r][c - 1] <= sq[r][c + 1] &&       // Square 4 <=  Square 6
        sq[r][c - 1] <= sq[r - 1][c]             // Square 4 <=  Square 2
)
        spmw1(r, c - 1);

else
   if
(c < dCol &&
(
(sq[r][c + 1] != '#' && sq[r][c + 1] != ' ') ||   // Square 6 Not
Equal to # or ' '
(sq[r - 1][c] != '#' && sq[r - 1][c] != ' ') ||     // Square 2 Not
Equal to # or ' '
(sq[r][c - 1] != '#' && sq[r][c - 1] != ' ') ||     // Square 4 Not
Equal to # or ' '
(sq[r + 1][c] != '#' && sq[r + 1][c] != ' ')      // Square 8 Not
Equal to # or ' '
) &&
sq[r][c + 1] <= sq[r - 1][c] &&      // Square 6 <= Square 2
sq[r][c + 1] <= sq[r][c - 1] &&      // Square 6 <= Square 4
sq[r][c + 1] <= sq[r + 1][c]          // Square 6 <= Square 8
)
      spmw1(r, c + 1);
 else
  if

......   It looks like a lot of your tests are duplicates, so you
might want to nest some of your tests.  For example...

If (( sq[r-1][c] != '#' && sq[r-1][c] != ' ') || (sq[r][c - 1] != '#'
&& sq[r][c - 1] != ' ') ||
    (sq[r][c + 1] != '#' && sq[r][c + 1] != ' ') ||(sq[r + 1][c] !=
'#' && sq[r + 1][c] != ' ') )
{
 if ( c < dCol ) && sq[r][c + 1] <= sq[r - 1][c] &&sq[r][c + 1] <=
sq[r][c - 1] &&
     sq[r][c + 1] <= sq[r + 1][c]  ) spmw1(r, c + 1);
else
 if ( c> dCol ) && sq[r][c - 1] <= sq[r - 1][c] && sq[r][c - 1] <=
sq[r][c + 1] &&
     sq[r][c - 1] <= sq[r + 1][c] ) spmw1(r, c - 1)
}


But I still can't even tell you what your code is trying to do.
