Reverse an array containing random numbers. How?-CodePudding

My assignment is to create an array with random numbers and then reverse the order in C#.

I managed to generate the random array, but how do i reverse it?

For example the output should look like this

15334 43351

int[] TalArray = new int[5];
var arr = new int[TalArray.Length];
for (int i = 0; i < TalArray.Length; i  )

{
    Random random = new Random();
    int num = random.Next(TalArray.Length);

    Console.WriteLine(num);
}

Thanks in advance! :)

Here is a solution with Array.Reverse:

var arr = new int[5];
for (int i = 0; i < arr.Length; i  )
  {
     arr[i] = new Random().Next(0, arr.Length);
  }
var revArr = arr.Reverse();
Console.WriteLine(String.Join("", arr )   string.Join("", revArr));

Have you tried Documentation

public static void Main()
    {
        int[] TalArray = new int[5];
        var arr = new int[TalArray.Length];
        for (int i = 0; i < TalArray.Length; i  )
        {
            Random random = new Random();
            int num = random.Next(TalArray.Length);
            arr[i] = num;
            Console.WriteLine(num);
        } 
        
        Array.Reverse(arr);
        for (int i = 0; i < arr.Length; i  )
        {
            Console.WriteLine(arr[i]);
        } 
    }
