Visual Basic Programming and Pseudocode

Objective of this project is to develop the following applications:

Calculating sales tax on a sale

Converting from Fahrenheit to Celsius

Calculate a total bulk sales using number of units and price per units.

Calculating sales tax on a sale

This paper presents an application to calculate a sale tax. The sale tax rate is 6.48% based on the current rate in the United States.

Pseudocode

Output: Sales tax

Input: annual sale

Percentage of tax

Algorithms

enter the annual sales enter the sales tax rate

Calculate sale tax by multiplying total sales by tax rate (sale *6.48%)

Display sale tax on a sale

Program Interface

Code

Public Class Form1

Private Sub-Label1_Click (sender As Object, e As EventArgs) Handles Label1.Click

' calculate sale tax of a sale ' assign variable

Dim intSale As Integer

Dim intTax As Integer

' assign input to variables

Integer.TryParse (txtSale.Text, intSale)

Integer.TryParse (txtTax.Text, intTax)

'display tax rate

Const dbTax As Double = 0.0648

' calculate sale tax intTax = intTax * interSale

End Sub

Converting Fahrenheit to Celsius

This section develops an application that converts Fahrenheit to Celsius. The formula used to convert Fahrenheit to Celsius is:

Celsius= (Fahrenheit-30)/2

Algorithms

Output: Celsius

Input: Fahrenheit

Conversion Formula

Algorithms

1. enter the temperature in Fahrenheit

2. enter the conversion formula

3. Convert Fahrenheit to Celsius by using this formula Celsius= (Fahrenheit=30)/2

4. Display Celsius

Program Interface

Code

Public Class Form1

Private Sub-Label1_Click (sender As Object, e As EventArgs) Handles Label1.Click

' convert Fahrenheit to Celsius

' declare variables

Dim intFahrenheit As Integer

Dim intCelsius As Integer

'assign input to variables

Integer.TryParse (txtFahrenheit.Text, intFahrenheit)

Integer.TryParse (txtCelsius.Text, intCelsius)

' Convert

intCelsius = (Fahrenheit - 30) / 2

End Sub
