Program : Go Left

You are to write a C program that will prompt the user to enter five points.

Each point has an integer value x and an integer value y.

The points are ordered: first, second, third, fourth, and fifth.

The first four points form a convex quadrilateral.

Your program should determine whether or not the fifth point is located inside the quadrilateral or not. A fifth point that lies on the quadrilateral is not inside of it.

Your output should be a sentence indicating whether the fifth point is within the quadrilateral or not.
