====

Part A
------
With regard to the maketest makefile. Explain the difference between
the behaviour of the two targets jane and oliver.

Part B
------
With regard to kwic-2012, determine the gcov line-coverage for each module.

Part C
------
With regard to the WordTable module and the file WordTable.c.gcov, modify
the test infrastructure such that lines 76 and 77 from WordTable.c.gcov
are executed at least once.

Part D
------
Replace the Makefile in stack_adt with the Makefile in
Stack-Makefile-Coverage. make coverage will produce the stack.pm.coverage
report.

Deliverables
------------

1. A verbal explanation of the PID output from targets jane and oliver
   using the maketest makefile.

2. A printed list containing the gcov line-coverage % statistic for each module.

3. A demonstration of make gcov yielding at least 69% line-coverage.

4. Comment on the constructor coverage in stack.pm.coverage.
