What is the best way to get the max value from the array and match it to other elements of the array?

Data example in array:

Lisa 76
John 82
Kate 59
Peter 74

I can get the max value from the array but it doesn't assign the correct name of the student to it.

I have following array and simplified structure:

`Dim students(3) As student`
```Structure student
Dim name As String
Dim Average As Double
End Structure```
```Private Sub btnfindMax_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnfindMax.Click
Dim i As Integer
Dim max As Double

max = students(i).Average

For i = 0 To Len(students(i).Average) - 1
If students(i).Average > max Then
max = students(i).Average
End If
Next

' A correct max value is assigned to incorrect student name
MsgBox(students(i).name & " " & max)

End Sub```

H!, Buddy

You want to max value with its student name, right ?

You store you data in array or any other tables or dataset.

You can find easily max value with that name.

Here no need to take variable Average.

First you need to find that Index of array in which stored max value, you also called that GetPostionsOfMaxValue

When you find index of max value, on that you get stored name and value of that particular index.
I hope you will understand, if any question so fill free comment on my answer.

Happy Coding Buddy.

## Solution 1

This line makes no sense and would not compile in "normal" language:
`max = students(i).Average`

First of all `i` is not assigned; second of all, you should not declare it, and finally, getting any element of the array for initial value of `max` won't make a correct algorithm. Instead do this:
`max = double.NegativeInfinity`

This special value will correctly compare using '<' operator (and other comparison operators) with any other double value except NaN and will serve as a correct initial value for maximum. Indeed, there won't be any number less then double.NegativeInfinity.

If you also need to use the `name` (or some other member of the `student` structure), you need to search not just for maximum, but also remember the index of the maximum element. If you think just a bit, you will easily modify the code the get it.
