Modify the program so it uses a named constant in place of $0\mathrm{.}049.$

$6.$ Run the program and test it to see if it gives the same values.

$7.$ Modify the interest rate to $0\mathrm{.}059.$

$8.$ Run the program again and test it to see the values it gives have changed.

$9.$ Did you change the output, so it now says $5\mathrm{.}9\%?$ If not make that change and run the

program again.

$10.$ Since it would be easier not to have to change the program in two places, declare a

new double variable called percent and set its value to $100$ times the interest rate.

$11.$ Modify your output statement so it uses the percent variable instead of $5\mathrm{.}9.$

$12.$ Run the program again and test it to make sure it still works properly.

$13.$ Add some additional statements to compute what the balance will be after a second

year of earning interest and display this result along with the original result
