$($This must be done in C sharpe programming$)$ In this assignment, you will write a program that prints a discount table. The output will be directed to a list box. Your interface will be a windows form that contains:

Label $-$ Start Value:

Textbox $-$ start$\_$value

Label $-$ End Value:

Textbox $-$ end$\_$value

Listbox $-$ discount$\_$table$\_$list

Button $-$ Display Table $($Name: display$\_$table$)$

When the button is clicked, the code will loop through the values, skipping odd numbers, beginning with the start value and ending with the end value, inclusive. Each time through the loop, the current value of the loop control variable will be tested to see what discount is relevant and will add a string to the listbox of the form current$\_$value has a XXX percent discount. Where current$\_$value is the current value of the loop counter and XXX is a calculated discount.

Here are the discount percentages:

$1-5$ items $-$ no discount

$6-10$ items $-5\%$

$11-20$ items $-10\%$

$21+$ items $-20\%$

Valid ranges of numbers are anything greater than $0$ and less than $100.$ Try different ranges and see how it works.
