Turtle Graphics

The turtle graphics is a classic and popular way to introducing programming to kids.

In the turtle graphics, you control a turtle to move around the graphics window. The traces left by its move form drawings.

In the following program, we use turtle graphics to draw a star:

In the main function, we:

1. use create_world(800,600) to create a 800x600 drawing canvas (drawing window)
2. set the pen color to red and the fill color to red
3. use right(90) command to turn the turtle 90 degrees clockwise.
4. use forward(100) command to move the turtle 100 steps forward,then turn the turtle 144 degrees clockwise.
5. repeat the above step 5 times
6. use close_world() to close the drawing window.
