Question

For C#

Scenario: Create a Windows Forms application that accepts the total cost of a sale and the amount submitted by the customer.

Calculate and display the correct change from largest denomination to smallest.

If the cost exceeds the amount submitted, post a message to the user that they have entered an invalid amount.

The program should accept both the cost and the amount submitted into textbox controls.

The program should use Try/Catch statements to keep the program from crashing.

Inputs:

1) The cost of a sale.

2) The amount submitted to pay for the sale.

Processing:

1. Calculate the correct change due to the buyer.

2. Display the correct change from largest bill to smallest coin.

Output:

Display a graphical representation of the bills/coins and the correct amounts of each.

Hint: You will need to use the modulus operator to determine the remaining amount after extracting the correct number of bills/coins from the previous amount

Answer 1

solution:

Please open visual studio and select File->New Project and from the new project dialog box select Other Languages->Visual C# and select Windows Forms Application. Enter a project name at the bottom of the dialouge box and click OK button.

After selecting Windows Forms Application , you can see a default Form (Form1) in your new C# project. The Windows Form you see in Designer view is a visual representation of the window that will open when your application is opened. you can drag the controls(Textbox,Labels,button) from

"ToolBox" onto your applications main form(Form1) and adjust their size and position.

Right side , keep a label as "SALE Amount" and against that text box to enter the amount. Then below that, keep a label as "Amount Received" and against that text box to enter the amount. Below you have "Calculate button" . Please double click it to write the logic of code when user clicked the button.

Logic must be

Change = Amount Received - Sale amount;

Change Denomination bill for the given change in picture 412.85

412.85 % 100 = 4

Remaining amount = 12.85

12.85%10 = 1

Remaining amount = 2.85

2.85%1 = 2

Remaining amount = .85

.85%.25 = 3

Remaining amount = .10

0.10%.10 = 1

This denomination bill value will be moved to Text box(drag them to form as mentioned above) against each currency

End
