For this lab you will continue working with the "robot world" program from chapter 7 of the text.

Make the following modifications:

• Change the program so a robot stops moving when it runs out of energy. (Problem 7.5.4 from the text).
• Change the program so that moving into some types of terrain gives the robot energy.

Turn in: To turn the program you will need to combine all three of your files into one file that you can use cscheckin to submit (see assignment 8). On a Unix computer you do this by taring the files together. Use the command:
tar -cvf lab12.tar lab12.cpp robot.h world.h
(note your main program may have a name other than lab11.cpp, use that file name instead of lab12.cpp). This will combine the files into one file called lab12.tar. Use cscheckin to turn in that file.
