-------------Problem------------
// Determines the value of a coin collection

-------------Analysis-----------
See page 60 for details
DATA REQUIREMENTS
  Inputs
	nickels(int)	--count of nickels
	pennies(int)	--count of pennies
  Outputs
	dollars(int)	-- number of dollars she should get
	change(int)	-- the loose change she should get
  Additional
	total_cents(int)	--the total number of cents
FORMULAE
  1 dollar equals 100 pennies
  1 nickel equals 5   pennies

--------------Design-------------

INITIAL ALGORITHM
1. read in counts of nickels and pennies
2. Compute the total value in cents
	2.1 total_cents is 5 * nickels + pennies.
3. find value in dollars and loose change
	3.1 dollars is the integer quotient of total cents and 100.
	3.2 change is the remainder when total_cents is divided by 100.
4. Display the output.
