** Name: 

** Filename: monetary.cpp

** Project #: Deitel & Deitel 2.51

** Project Description: Modify the program in Fig 2.21 so it uses only
		   integers for monetary values to calculate the compound 
		   interest.

** Output: Table with year and amount of deposit as it grows  with 
           interest rate

** Input:  None

** Algorithm: Make all variables for money values as integers, then
              put into penny amount.
			  Run loop till year <= 10
			  Calculate yearly amount using formula a = p ( 1 + r )^n
			  Divide amount by 100 giving an integer result 
			  Divide amount using modulus to get remainder to add
			  cents amount 
			  Print amount followed by period then print cents
			  End program
