a)I am working on a payroll program The first base class is bonus the class should contain 2 public properties salesid and sales.
Include a default constructor and a parameeterized constructor in the class.Also include a a getbonus method(function) that calculates a salespersons bonus using the formula sales*0.05
b) create a derived class named Premiumbonus the derived clas getbonus mothod calculate the bonus as follows sales0.05 +(sales-2500)).01 also include a default and parameterized constructorin this derived class.
if the sales is over 2500 use this
I feel like my math is off and I need some suggestions and also i tried to debug and getbonus seems like it stays on 0 no matter what number i put but I get results in the calculated box.
below is the code
Option Explicit On Option Strict On Option Infer Off ' base class Public Class Bonus Public Property SalesId As String Public Property Sales As Double Public Sub New() _Sales = 0 _SalesId = String.Empty End Sub Public Sub New(ByVal dblB As Double, ByVal strId As String) _Sales = dblB _SalesId = strId End Sub Public Overridable Function GetBonus() As Double ' returns sales Return _Sales * 0.05 End Function End Class ' derived class Public Class PremiumBonus Inherits Bonus Public Sub New() MyBase.New() End Sub Public Sub New(ByVal dblB As Double, ByVal strId As String) MyBase.New(dblB, strId) End Sub Public Overrides Function GetBonus() As Double Return MyBase.GetBonus + (Sales - 2500) * 0.01 End Function End Class Private Sub btnCalc_Click(sender As Object, e As EventArgs) Handles btnCalc.Click ' calculates and displays a bonus Dim myBonus As New Bonus Dim myPremiumBonus As New PremiumBonus Dim Sales As Double ' if the sales are over $2500, instantiate a PremiumBonus object ' and then calculate the bonus ' otherwise, instantiate a Bonus object and then calculate the bonus If Sales > 2500 Then Double.TryParse(txtSales.Text, myBonus.Sales) Sales = myBonus.GetBonus Else Double.TryParse(txtSales.Text, myPremiumBonus.Sales) Sales = myPremiumBonus.GetBonus End If
