Design the following programs. See samples

Programming language the visual studio

Program Design 1 - Credit

A retail store gives each of its customers a maximum amount of credit based on the customers credit history. A customers available credit is determined by subtracting the amount of credit used by the customer from the customers maximum amount of credit. Design an application that determines the customers available credit.

Program Design 2 - Discount

Design a program that determines the discounted price of an item, given the original price and a discount per cent. The user wants a discount per cent of, say 5%, to be entered as 5, not .05

Each design should include:

Define what the program is to do

Design the user interface

List the controls needed and define the values of each controls relevant properties. Follow the naming standards for the controls listed below. This week, were only interested in the Name and Text properties:

List the methods needed for each control

Naming standards for controls:

Control names consist of a root and a suffix

The suffix identifies the control type

The root is always mixed-case, starting with a small letter

Never use underscores in control names

Control type	Example
Button	changeFormNameButton
Form	customerForm
Label	helpMessageLabel
Textbox	customerLastNameTextBox

You arent required to name identifying labels (labels not used in your code)

You can just use the default, Label1, Label2, etc. for this.

You are required to name the form, something the book doesnt do until later. Get into the habit of naming forms early.

This is a sample of the design document required for assignment 1. Sample Challenge You have been asked to create an application for a carpet sales and installation business. The application should allow the user to enter the length and width of a room and calculate the room's area in square feet. The calculation is Area = Length x width Step 1 Clearly define what the application will do. Purpose: To calculate the area of carpet used in a rectangular shaped room. Output: Carpet size Input: Length and width of a room Process: Multiply length by width (result is carpet size) Step 2. Design the GUI Length | ?
