CS12, Lab 6

Week of February 11-February 15

Topics:

· Debugging programs

· Using the debugger

· Recursion

To do:

· Listen carefully as your TA describes the use of the debugger. Take copious notes, especially if you are a CS major. As your programs and projects become more complex, you will be relying on debugging tools more heavily. This topic will not, to the best of my knowledge, be covered in any other class. Use this opportunity well.

· Copy the files bug1.h , bug1.cc , mainbug1.cc , bug2.h , bug2.cc , mainbug2.cc , bug3.cc and makefile into a directory. There are three buggy programs in all, and a makefile that works for all of them. Compile and run each program (the makefile has instructions on how to do this), then try to find the bugs. There are to do lists, comments and hints in the files themselves. Please use the debugger, unless the you can spot the problem by looking at the code for less than a minute. Solve any two problems for full credit (5 points each), the fourth for extra credit (3 points).
