Lab 1 (Due Thursday February 27)
Write a program that includes a procedure (module; subroutine) that tests whether two straight line segments (defined by their end points) intersect. It should determine (return) both
A: (4,2), (2,0); (4,0),(0,4)
B: (1,0), (1,4); (0,2), (3,3)
C: (1,4), (5,2); (0,-1), (2,3)
D: (1,0), (3,2); (4,3), (6,5)
E: (0,4), (2,2); (2,2), (4,1)
Hand in the program listing, the test data, and the output.
