    Consider the following problem statement:
A person invests $1000.00 in a savings account
yielding 5 percent interest. Assuming that all
interest is left on deposit in the account,
calculate and print the amount of money in the
account at the end of each year for 10 years.
Use the following formula for determining
these amounts:

	a = p (1 + r)^n

Where
	p is the original amount invested (i.e., the principal)
	r is the annual rate,
	n is the number of years, and
	a is the amount on deposit at the end of the nth year

This problem involves a loop that performs the
indicated calculation for each of the 10 years
the money remains on deposit
