Find intersection of the line with rectangle's sides. Then find if these intersection points belong to the segments of the rectangle.

I know , and also i write code of it but it didn't work.
Can you explain it with code?
Thanks

It's very unlikely that I will code and test the solution to the task like this only to send it to you and then discard. If you have some code (checking for intersection? intersection belonging to the segment?) post it here with test cases that show that it doesn't work.
