A Note:

Please note that this page indicates precisely what your program should accomplish, without a precise indication of how the program works. Part of your assignment is designing the techniques of how the program works.

What the Program Should Do

This program use the winbgim library for graphics and mouse support.

When the program begins, it opens a graphics window that contains one elliptical eye with a round green iris inside. The iris follows the mouse whenever the mouse enters the graphical window. To be more precise: Whenever the mouse is in the window, the iris should move to an edge of its ellipse so that there is a straight line from the center of the ellipse through the center of the iris and on to the mouse pointer.

Also, whenever the user clicks the left mouse button inside the window, the center of the eye moves to the location of the click. And whenever the user clicks the right mouse button inside the window, the iris changes color.

Here is some of the mathematics that may help you:
