### Simple Animation Using C

Here i have used fillpoly function to draw the object body and used fillellipse function to draw tier.
animation is done by looping through the objects x & y position until user hits a key. Keypress event is achived  by using kbhit function. Smoothness of animation is controlled by delay function.

Change the delay values to change the animation speed
