Orga: Hewlett Packard, Cupertino > I always thought that an interesting use for the comma was in a for > loop when one wanted, say, to create the identity matrix: I agree completely. However the following code: > float array[SIZE][SIZE]; > int i,j; > > /* initialize the whole thing to zero, then to this: */ > for(i=0,j=0; i<SIZE; i++, j++) > array[i][j] = 0; creates the following matrix: 0 garbage garbage garbage ... garbage garbage 0 garbage garbage ... garbage garbage garbage 0 garbage ... garbage . . . . ... . : : : : ::: . garbage garbage garbage garbage ... 0 ...which is not precisely what I wanted.
