Some help...

Adam Wike

How would I get a program to show the numbers it adds up? Say the user wants the program to add numbers 1 through 10. How would I get the result to show up as "1+2+3+4+5+6+7+8+9+10=55"? I dont have a problem getting the program to add the numbers or anything. I just need help displaying the result, if it's any help I'll be using a loop. If I havent explained myself well enough let me know. Thanks :)

rawr!

you want the output to contain two things: a string representing the operands and operations, and the evaluation result. Hence your loop should contain two things: a concatenation adding the latest operator and operand to the symbolic string, and an addition adding the addend to the partial sum. :)

Sub Main()

Dim txt As String = ""
Dim arr() As Double = {20, 11, 34, 25, 55, 89}
Dim tot As Double = 0

For i As Integer = 0 To 5
  If i < 5 Then
    txt &= arr(i).ToString("0")
    txt &= "+"
    tot += arr(i)

  Else

    txt &= arr(i)
    txt &= "="
    tot += arr(i)
    txt &= tot.ToString("0")
  End If



Next

Console.WriteLine("Output: {0}", txt)
Console.Read()
End Sub

End Module
