Cant tell what im doing wrong no matter what numbers i enter it always return as a F and I cant get the average to calculate correctly plz help i uploaded the file also
Below is the assignment
Create an application that allows a teacher to enter three test scores each of the three students. The application should calculate each student’s average score and assign a letter grade based on the following grading scale:
Average Test Score Letter Grade 90 or greater A 80 through 89 B 70 through 79 C 60 through 69 D Below 60 F
The application should prompt the user for each students name and three test scores. A box needs to appear after all the data has been entered showing the results.
Public Class Form1 Private Sub btnEnter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnter.Click ' Assigning variable as a string for student name Dim studentName As String Dim strScore As String Dim result As String ' Assigning Test Scores as a Decimal Dim numScore As Decimal ' Assnumigning average as a decimal Dim average As Decimal ' Assigning counter for repeatable names Dim counter As Integer = 1 ' Assigning counter for Test scores Dim scoreCounter As Integer = 1 For counter = 1 To 3 ' Prompting user to enter names studentName = InputBox("Enter Student name" & counter, "Students name") numScore = scoreCounter + scoreCounter + scoreCounter ' Asking for the three given socres For scoreCounter = 1 To 3 ' Prompting user to enter students test scores. strScore = InputBox("Enter Score " & scoreCounter, "Students Score", " ") If strScore = "" Then ' Canceling the operation. MsgBox("You have cancelled the grading process") Exit Sub End If If Not IsNumeric(strScore) Then scoreCounter -= 1 ' Making sure the scores are numeric to prevent any errors. MsgBox("Score has to be numeric..." & vbCrLf & "Click ok and enter score again") Else End If Next average = numScore / 3 ' Giving the end result and averages for the 3 students result &= studentName & "'s Average Grade is:" & calcGrade(average) & vbCrLf Next MsgBox(result, MsgBoxStyle.OkOnly, "Results") End Sub Private Function calcGrade(ByVal avg As Decimal) As String ' Assigning Grade values for the test scores If avg >= 90 Then Return "A" ElseIf avg >= 80 Then Return "B" ElseIf avg >= 70 Then Return "C" ElseIf avg >= 60 Then Return "D" ElseIf avg < 59 Then Return "F" End If End Function End Class
