Turtle Graphics

Imagine a mechanical turtle that walks around the room under the control of a VB program. The turtle holds a pen in one of two positions, Up or Down. While the pen is down, the turtle traces out shapes as it moves; while the pen is up, the turtle moves about freely without writing anything. In this problem you will simulate the operation of the turtle and create a computerized sketchbook as well.

Use a 20-by-20 array **floor** which is initialized to zeros. Read commands from any array that contains them. Keep track of the current position of the turtle at all times and whether the pen is currently up or down. Assume that the turtle always starts at position 0,0 of the floor with its pen up. The set of turtle commands your program must process are as follows:

## Platform

Command Meaning

1 pen up

2 pen down

3 turn right

7 turn left

5, 10 move foward *n* spaces (in this case 10)

6 print the 20-by-20 array

9 end of data (sentinel)

As the turtle moves with the pen down, set the appropriate elements of array **floor** to 1's. When the 6 command (print) is given, wherever there is a 1 in the array, display an asterisk. Wherever there is a zero, display a blank. Write a program to implement the turtle graphics capabilities discussed here.
