how do I print a reverse order of these numbers in this while loop

[sports0028]

Hello how do I print a reverse order of these numbers in this while loop. I'm using array.

  Sub Main()
        Dim data() = {30, 32, 81, 43, 58, 85, 23, 19}
        Dim i = 0
 
        While (i > 8)
 
            Console.WriteLine(data(i))
            i = i + 1
 
        End While
    End Sub

well - if you have to use the while loop then 1st you would need to make sure it runs at all - the condition in line 5 is never met - so fix the comparison. now - i is counting up and so you just would need to access the elements from the end in that kind of loop - which basically means that you could use something like (Pseudocode here):

indexOfElementInTheLoop = (data.Length - 1) - i

a much cleaner way here would probably be a For-loop though - where you count down from the array's length-1 to 0 and you may use the counter directly to access the elements.

Use a For-Next loop:

Sub Main()
 
    Dim data() As Integer = {30, 32, 81, 43, 58, 85, 23, 19}
    Dim index As Integer
 
    For index = data.Length - 1 To 0 Step -1    
        Console.WriteLine(data(index).ToString())
    Next
 
End Sub

Try This Code

#include <stdio.h>
int main() {
    int n, rev = 0, remainder;
    printf("Enter an integer: ");
    scanf("%d", &n);
    while (n != 0) {
        remainder = n % 10;
        rev = rev * 10 + remainder;
        n /= 10;
    }
    printf("Reversed number = %d", rev);
    return 0;
}

Output

Enter an integer: 1234
Reversed number = 4321
