Trying to create the following sales tax program in Microsoft Visual

REQUIREMENTS DOCUMENT

Purpose:

This Windows Desktop application will compute the sales tax and final cost of a purchased item.

Program Procedures:

From a window on the screen, the user enters the item name and cost of the item purchased. The program calculates the tax for the item and the final total and then displays these values.

Algorithms, Processing, and Conditions:

1. 1. The user must be able to enter the name of the item purchased and the cost of the item before tax.
2. 2. A store name and store picture will be displayed throughout the entire process.
3. 3. After the user enters the item name and the cost of the item, she taps or clicks the Display Cost button.
4. 4. The program displays the item name with the cost, tax, and final total.
5. 5. The cost, tax, and final total should appear in currency format.
6. 6. The tax rate for all items is 8.75%.
7. 7. The final total is calculated by adding the cost and the tax.

Notes and Restrictions:

1. 1. The user can clear the item name, cost, tax, and final total with a Clear button.
2. 2. The user can tap or click an Exit button to close the application.

Comments:

The store picture shown in the window should be selected from pictures available on the web.
