+/* 
+Consider the software that runs on a self-checkout machine.  
+One task that it must be able to perform is to determine how much change to provide when the shopper
+pays for a purchase with cash.  
+
+- Write a program that begins by reading a number of cents from the user as an integer.  
+- Then your program should compute and display the denominations of the coins that should be used
+to give that amount of change to the shopper.  
+
+- **The change should be given using as few coins as possible.**
+
+- Assume that the machine is loaded with pennies, nickels, dimes, quarters, loonies and toonies.
+
+- Penny = 1 cent
+- Nickel = 5 cents
+- Dime = 10 cents
+- Quarter = 25 cents
+- Loonie = 100 cents
+- Toonie = 200 cents
+
+Example:
+742 cents = 3 toonies, 1 loonies, 1 quarters, 1 dimes, 1 nickels, 2 pennies.
