Hello daniweb folks. I am here to ask some guidance, tips, suggestions and advices regarding the round robin scheduling algorithm. We are tasked to solve for the waiting time and turn around time of each process. They all have the same arrival time which is zero.

here is my codes:

```
For y = 0 To numPro - 1
burstT(y) = Val(txtBT(y).Text)
remains(y) = burstT(y) - quantum
If burstT(y) = quantum Then
If txtBT(y).Index = 0 Then
lblWT(y).Caption = 0
lblTA(y).Caption = Val(lblWT(y).Caption) + Val(txtBT(y).Text)
Else
lblWT(y).Caption = quantum
lblTA(y).Caption = Val(lblWT(y).Caption) + Val(txtBT(y).Text)
End If
End If
Next
For z = 0 To numPro - 1
If remains(z) <> 0 Then
If remains(z) >= quantum Then
remains(z) = remains(z) - quantum
ElseIf remains(z) < quantum Then
remains(z) = remains(z) - remains(z)
End If
End If
Next
For x = 0 To numPro - 1 'calculating waiting time
If burstT(x) <> 0 Then
For num = x To numPro - 2
remain = remain + quantum
Next
End If
remained(x) = remain 'calculations stored them in the array
Next
```

My problem is that when I calculate for the waiting time, it is sometimes below the true answer or above the true answer.

Please guide me awesome daniweb folks. This ignorant me needs your brilliant minds. Any kind of help is very much appreciated! Thanks for reading this! :)
