Chapter 3, Problem 29PE
Program Plan Intro
Create a code that asksthe user to input 3 points or measures in the code (p0, p1, and p2), shows p2 is on which side of the line.
Program Plan:
Develop a program in C++ that asks the user to input three points or measures in the code (p0, p1, and p2) and finds if p2 is at the left or right side of the line or on the line p0 to p1.
The conditions for deciding are as follows.
ï‚· If (xl - x0) * (y2 - y0) - (x2 - x0) * (y1 - y0) > 0, p2 is on the left side.
ï‚· If (xl - x0) * (y2 - y0) - (x2 - x0) * (y1 - y0) = 0, p2 is on the same side.
ï‚· If (xl - x0) * (y2 - y0) - (x2 - x0) * (y1 - y0) < 0, p2 is on the right side.
