If you want to determine "Manhattan" movement (cardinal directions only, make only one turn en-route to a given unmoving target point) on a step-by-step basis, you have to choose whether you prefer to move horizontally first, or vertically first.

if ( cX != dX ) {
if ( cX < dX )
cX += 1;
cX -= 1;
} else {
if ( cY < dY )
cY += 1;
cY -= 1;

That's for preferring to move across before up and down. Read cX = Current X, dX = Destination X.
