Homework 11
Maximum Points: 6 (plus a possible 3 bonus points)
Due 9:00 am, Thursday, December 4, 2003

Copy this file to a text file named hw11.txt, edit into it your
answers, and submit the file via the submit program by the deadline
given above.

1. (3) In the class web notes on Subprograms
(http://www.cse.buffalo.edu/~shapiro/Courses/CSE305/notes10.html), in
the section on "Function Parameters", there is a C function called
printTable.  printTable takes a function and an array, and
prints a table of the integers in the array and the results of calling
the function on that integer.  printTable is tested in main by passing
it a doubling function and a squaring function, each with an array of
the integers 1 - 5.  Write a Java version of this C program.  Come as
close as you can to copying the style of the C program.  Hint:
Consider an abstract class with one method called Apply.  If f is an
object of this class, consider f.Apply(5).  Include below this
paragraph your program and a copy of your test compile-and-run.

2. (3) Do Problem 6 of Chapter 13 of the text (page 539-540).  For
each possible different final value of Buf_Size, you only need to show
one sequence of events.

3. (3 bonus) Write a Prolog program, so that, if you query a month
number, N, the program prints the name and length of the Nth month.
For example,
     | ?- month(5).
     May has 31 days.
     yes
Note: an appropriate printing relation is
     format("~s has ~d days.~n", [Name, Length])
There must be only one occurrence of the format predicate in your program.
Include below this paragraph your program and a copy of your test run.
