Homework 8 Solution
UCR CS10: Introduction to Computer Science
Winter Quarter 2004, Lecturer: Kris Miller

Due Wednesday, March 3 before 8:00pm by web turnin.

YOU MUST TURN THIS IN AS A .CPP, .CC, OR .C FILE. The turnin system will no
longer accept other types of files. Your file names should not have spaces
or non-alphanumeric characters. A good file name to use is hw7.cpp.

-------------------------------------------------------------------------------
Note: Collaboration policy for this homework assignment

Collaboration on this homework is strongly ENCOURAGED. The homework is intended
for practice, not assessment -- most people who turn in decent work should get
most if not all points for this assignment. Forming study groups is strongly 
encouraged. You shouldn't simply copy answers from any source -- each other,
the book, the web, other books, previous solutions, etc. But you can certainly
discuss how to solve the problems, look over each others solutions and help
"debug" them, compare answers and redo problems if you determine your answer is
wrong, and most importantly, explain concepts related to the problems and
solutions.
