Function MinMaxArray

Objetive

Write a Visual Basic (VB.Net) function named MinMaxArray, to return the minimum and maximum values stored in an array, using reference parameters:

float[] data={1.5f, 0.7f, 8.0f}
MinMaxArray(data, ref minimum, ref maximum);
(after that call, minimum would contain 0.7, and maximum would contain 8.0)

Code

Imports System
Public Class exercise127
    Public Shared Sub MinMaxArray(ByVal number As Single(), ByRef min As Single, ByRef max As Single)
        max = number(0)
        min = number(0)

        For i As Integer = 1 To number.Length - 1
            If number(i) > max Then max = number(i)
            If number(i) < min Then min = number(i)
        Next
    End Sub

    Public Shared Sub Main(ByVal args As String())
        Dim data As Single() = {3.5F, 0.5F, 9, 0F}
        Dim min As Single = 0.0F
        Dim max As Single = 0.0F
        MinMaxArray(data, min, max)
        Console.WriteLine("Minimun: {0} - Maximun: {1}", min, max)
    End Sub
End Class
