#define setvalue(matrix, row, col, value) ( matrix[row+col] = value)
//roughly looks like this
row + col ?
0 + 3 = 3 + 0
and obviously is not what you want...
((row * 4) + col)
((0 * 4) + 3) == 3 and ((3 * 4) + 0) == 12
+
row and col being indices in an array
should be int not double...
(#define are not a good idea for this kind of application..., just an
opinion)
