Can someone please check the code below and mention the problem area.

C#
<pre>static void Main(string[] args)
        {
            Console.Write("How many nums to be compared: ");
            int n = int.Parse(Console.ReadLine()); //Parse int n for arr.Length
            int[] arr = new int[n]; //Creates array with name arr and length n
            Console.WriteLine("Enter the nums: "); //To be used while entering elements

            //Registers array elements
            for (int arrIndex = 0; arrIndex < arr.Length; arrIndex++)
            {
                arr[arrIndex] = int.Parse(Console.ReadLine()); //Parse array elements
            }

            //Prints array
            for (int arrIndex = 0; arrIndex < arr.Length; arrIndex++)
            {
                Console.Write(arr[arrIndex] + " ");
            }
            Console.WriteLine();

            GetMax(arr);
        }

        static void GetMax(int[] array)
        {
            if ((array[0]) > (array[1]))
            {
                Console.Write("Number {} is > than {}", array[0], array[1]);
            }
            else if ((array[0]) < (array[1]))
            {
                Console.Write("Number {} is < than {}", array[0], array[1]);
            }
            else
            {
                Console.Write("Number {} and {} are equal", array[0], array[1]);
            }
        }}


What I have tried:

I tried re-reading the complete chapter on methods from the book I'm learning C# but couldn't find any reason.

I'm an absolute beginner so I request to please keep the explanation very very simple.

It gives me the following error when I run the code

How many nums to be compared: 2
Enter the nums:
1
5
1 5

Unhandled Exception: System.FormatException: Input string was not in a correct format.

Your problem is in the Console.Write function - you forgot to put the index for the variable to be shown in the output. You should also add a Console.ReadKey(); call at the end of the Main method because you will, otherwise, not see the output when you start the program from Visual Studio...

C#
static void GetMax(int[] array)
        {
            if ((array[0]) > (array[1]))
            {
                Console.Write("Number {0} is > than {1}", array[0], array[1]);
            }
            else if ((array[0]) < (array[1]))
            {
                Console.Write("Number {0} is < than {1}", array[0], array[1]);
            }
            else
            {
                Console.Write("Number {0} and {1} are equal", array[0], array[1]);
            }
        }

Thanks, strange - I cannot see a reason for voting this with 1 star?

It looks like it happened again:

This makes me wonder if this is the same person maybe trying to resolve a personal issue with me or CP ...?

yep
Thanks for pointing that out.

Next time i will be more attentive while rechecking my codes.

Thanks again. Yes the program is working now.
