SOFTWARE ENGINEERING QUESTION:-

ign black-box test suite for the following program. The program accepts two pairs cf co-ordinates (xl,yl),(x2,y2), (x3,y3), (x4.y4). The first two points (x1,yl) and (x2.y2) second two points (x3,y3) and (x4,y4) represent the lower left and the upper right points of the second rectangle. It is assumed that the length and width of the rectangle are parallel -axis or y-axis. The program computes the points of intersection of the represent the lower left and the upper right points of the first rectangle. The to either the x two rectangles and prints their points of inter
