In this exercise, you$$ll develop an application that tells how many quarters, dimes, nickels, and pennies

are needed to make change for any amount of change from $0$ through $99$ cents. One way to get the results

is to use the divide and modulus operators along with the parseInt$()$ method for truncating the results so

they are whole numbers.

$1.$ Open the application in this folder:

ch$04\backslash$change$\_$maker$\backslash$

Then, run the application to see the user interface shown above, although that interface won$$t do

anything until you develop the JavaScript for it$.$ In the JavaScript file, note that the $$()$ function has

already been coded.

$2.$ Code an event handler named processEntry$()$ that gets the user$$s entry and checks to make sure that

it is a number between $0$ and $99.$ If so$,$ call a function named makeChange$()$ and pass it the user$$s

entry. Otherwise, display an alert dialog box for the error.

$3.$ Code the makeChange$()$ function, which should have one parameter that accepts the user$$s entry.

This function shouldn$$t return anything, but it should display the results in the text boxes for

Quarters, Dimes, Nickels, and Pennies.

$4.$ Code a DOMContentLoaded event handler that attaches the processEntry$()$ event handler to the click

event of the Make Change button. Then, test this application.

$5.$ Save your files in the folder above.
