Upload the code

In this assignment, you'll add code that calculates the number of nights, total price, and average price for

a reservation based on the arrival and departure dates the user enters.

Open the project and implement the calculations

Open the Reservations project attached here with this assignment and review the code for

the form. Notice that it contains event handlers for the click events of the Calculate and

Exit buttons, plus several data validation methods.

Modify the Click event handler for the Calculate button so it gets the arrival and

departure dates the user enters. Then, calculate the number of days between those dates,

calculate the total price based on a price per night of $$120,$ calculate the average price per

night, and display the results.

Test the app to be sure it works correctly. At this point, the average price will be the same

as the nightly price.

Enhance the way the form works

Add an event handler for the Load event of the form. This event handler should get the

current date and three days after the current date and assign these dates to the Arrival

Date and Departure Date text boxes as default values. Be sure to format the dates as

shown above. $5.$ Modify the Click event handler for the Calculate button so Friday and Saturday nights are

charged at $$150$ and other nights are charged at $$120.$ One way to do this is to use a while

loop that checks the day for each date of the reservation.

$6.$ Test the app to be sure that the default dates are displayed correctly and that the totals are

calculated correctly.

Add code to validate the dates

$7.$ Add code to the IsDateTime$()$ method that checks that a value is a valid date.

$8.$ Add code to the IsWithinDateRange$()$ method that checks that a value is within a date

range that includes the minimum and maximum dates that are passed to it$.$

$9.$ Add code to the IsLaterDate$()$ method that compares the two values passed to it and

makes sure the second value is later than the first value.

$10.$ Add code to the IsValidData$()$ method that uses the IsDateTime$(),$ IsWithinDateRange$(),$

and IsLaterDate$()$ methods to validate the arrival and departure dates. These dates should

be in a range from the current date to five years after the current date, and the departure

date should be later than the arrival date.

$11.$ Modify the Click event handler for the Calculate button so it uses the IsValidData$()$

method to validate the arrival and departure dates.

$12.$ Test the app to be sure the dates are validated properly.
