Supplementary Assignment:
Enhancements to the Aquarium Program

For this assignment you will enhance the Aquarium program.

• Complete any unfinished exercises from the Lab on Displaying the Aquarium Using Graphics and the two Mini-Labs (Staying In Bounds and Adding Color and Keep on Moving).

• Add support for more fish colors in display.cpp. Test them by using different initial colors of fish as you construct them and re-running the program. You may also wish to explore different colors for the water in the aquarium. You can find color names in colors.h in the CMU graphics library.

• Look at the CMU graphics demo program to see how to use Pause rather than WaitNClear. Update your program to use this function to get a smoother simulation. Keep a call to WaitNClear at the end of your program so that the simulation doesn't just disappear. Don't forget to #include the appropriate header file to use Pause. (You will need to search for Pause in the demo program to find both the proper #include statement and examples of how the function is called.)

  NOTE: you may wish to comment out the call to WaitNClear, rather than remove it, in case it comes in handy at a later date.

• Give each fish a 1 in 4 chance of changing direction, rather than a 50/50 chance (unless, of course, the fish is at a wall, in which case it must change direction).

• Update the documentation and comments in your program (main.cpp and display.cpp) to conform to the guidelines and standards for your class.

• Save and print your work.
