UCR CS10: Introduction to Computer Science
Spring Quarter 2004, Lecturer: Kris Miller

Due Wednesday, May 5 before 8:00pm by web turnin.

-------------------------------------------------------------------------------
Turnin:

Turnin this assignment to the folder, hw4, using the electronic turnin linked
to from the class webpage. For homeworks only, you may turnin .doc (Microsoft
Word) or .txt (Notepad) files. You may also turnin the homework as a .cc or
.cpp (C++ source) file. Be sure to turn it into the correct folder. At best,
you will be penalized 20%. At worst, your homework may not be graded at all.

-------------------------------------------------------------------------------
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.

10. CodeMate Problem #8 from Chapter 4


void convertToPounds(double kilograms, double grams, 
                     double& pounds, double& ounces)
{
     double total_weight_kilograms, total_weight_pounds;

     // converts the entire weight entered by user to just kilograms
     total_weight_kilograms = kilograms + (grams / gramsPerKilogram);

     // converts the entire weight to pounds
     total_weight_pounds = total_weight_kilograms * poundsPerKilogram;

     // removes fractional part of pounds (floor in cmath library)
     pounds = floor(total_weight_pounds);

     // converts the leftover fractional part to ounces
     ounces = (total_weight_pounds - pounds) * ouncesPerPound;
}
