# Array - Function with no argument

How do I call a function that takes no argument and returns the average total of the array.

This is what I have come up with:

Public Function Average() as Decimal ={87.5D, 95.25D, 26.50D, 74.45D}
Dim Average as Decimal
Dim Number as Integer
Dim Total as Decimal
If  Number = 0 to 3 then
Average = Total/Number
Return Convert.ToDecimal (Total/Number)
Else
End If
End Function

Hi thimss2,
Sorry, does not make sense..
Since you are not passing any arguments, Number will always be zero.
Your function probably will throw a division by zero error.

This the function I created. Nnow want to create an array that calls a function that takes no argument and returns the average total of the array.

Public Function Average(ByVal Total as Decimal, ByVal NumberAs Integer) As String

If Number AndAlso Total > 0 Then
Return Convert.ToString(Total / Number)
Else
Return "Error"
End If

End Function

' procedure which passed the argument
Sub DisplayAvg(ByVal Total as Decimal, ByVal Number as Numberas Integer)
MessageBox.Show("Average  " & Average(Total, Number)
End Sub

Or Should I leave it as:
Public Function Average()
Return Convert.ToDecimal (Total/Number)

Thanks

I do not understand what you mean by:

"an array that calls a function"

What you MIGHT be talking about is creating a new class, that consists of an array or a collection and returns the average.

thimss2,
OK! Before I get into this, I need to know how much you know about classes if at all

My knowledge of classes is very limited. I am a beginner. I know how to create a new class.

Thanks

thimss2,
Lets take it one step at a time.

Create a new class as follows:

Public Class cMyArray
Dim myArray() As Integer
Private mNumberofItems As Integer = 0
Public Sub AddToArray(ByVal NewNumber As Integer)
ReDim Preserve myArray(mNumberofItems)
myArray(mNumberofItems) = NewNumber
mNumberofItems += 1
End Sub
End Class

This is just the first step, but it has to be clear to you before we continue.
See if you can continue by yourself first, before you ask for the next step, and show me what you have tried.
