If $10,000 is invested at an annual interest rate r compounded n times per year, then the amount of the investment after
five years will be
Some possible values for r are .02, .025, .03, .035, and .04. Some
possible values for n are 1, 2, 4, 12, and 52. Write a program that
allows the user to select interest rates and compounding periods from
list boxes and calculate the amount after five years. See Fig. 10.1.
Note: Normally, if there are two list boxes in the window, when you
select a value in one, it deselects whatever you selected in the other.
However, this behavior will not occur if the argument
exportselection=0 is inserted into each list box’s constructor.
