Testing Video For Lab 3

For this lab you may create your own interface similar to the following or use the Lab 3 shell provided in the Shell folder in Angel.

Your task is to

• Add code to calculate the amount of change owed to a customer given the Amount Due and Amount Paid and determine the number of dollars, quarters, dimes, nickels, and pennies to be returned to the customer when the user clicks the Determine Change button. Display the results in Labels.

• Clear all TextBoxes and Labels when the user clicks on the Clear command button.

• End the program when the Exit button is clicked

Additional Requirements

• Turn Option Strict On
• Return Focus to the first TextBox after clicking either command button. Use the Focus method.
• Use the Convert Class to convert the input entered in the TextBoxes to numbers.
• Do NOT do any math using controls. Use variables instead.
• Format the change amount as currency.

Remember to

• Make sure the project, form, and all controls have appropriate names.
• Use appropriate names for variables.
• Include your name in the Text property of the form

Hints

• Refer to the flowchart and pseudo code provided on the week’s details page.
• If you divide the number of cents to be returned by 100 the quotient will be how many dollars are to be returned and the remainder will be the amount to be returned as coins.
• When using integer division (\)  and modular division (mod) all operands should be Integers.
• Do not be concerned with the possibility that the amount paid is less than the amount owed.
• Formatted negative values appear in parenthesis.
• Look for patterns.

When you are confident the program works

· Include comment lines (any line that begins with an apostrophe (‘) is treated as a comment) in the general declaration section (That means at the top of your program) with the following information

o your name

o a brief description of what the program does 

o A record of how much time you spent on the lab

· Zip up and submit as an attachment in the appropriate drop box.
