VB.Net Compute Tips For Services Rendered. Beginner.

Question

The program should request the person’s occupation, the amount of the bill, and the percentage tip as input and pass this information to a Sub procedure to display the person and the tip. Title is gratuities, first line Person’s occupation, amount of the bill:, Percentage tip: Compute Tip, and show the tip. Im not sure how to approach it properly. Any help is greatly appreciated.

Public Class Form1

Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As _
    System.EventArgs) Handles btnCompute.Click

    Dim Occupation As String = CStr(txtOccupation.Text)
    Dim Bill As Double = CDbl(txtBill.Text)
    Dim Tip As Double = CDbl(txtTip.Text)

    lstOuput.Text = 'hmmmmm.....'



End Sub

End Class

Answer 1

lstOutput.Text = Bill * (1 + If(Tip<1,Tip,Tip/100))

Answer 2

Since you have assigned the Bill and Tip to double variables, you can assign the gratuity amount into another variable, or output it directly.

Dim Gratuity as Double = Bill * Tip

lstOutput.text = "Total Bill + Gratuity = " & string.format(Bill + Gratuity, "c")
