/***************************************************
Compound Interest
Write a program that reads an annual interest rate
and a term (number of years) from the user, and
computes the ammount of money you'd have after that
number of years at that interest rate, assuming you
make $100.00 payments into the account at the
beginning of each year.
The formula for interest is this: If A is the
amount of money in your account at the beginning of
the year, and r is the annual interest rate, the
amount in your account at the end of the year is:
A*(1.0 + r/100.0)

// Read number of years
