I asked this once before but it came up incorrect somehow so I'll submit this one again. Write a program in C# named ArrayDemo that stores an array of 10 integers. (Note that the array is created for you and does not need to be changed.)Until the user enters a sentinel value, allow the user four options:(1) to view the list in order from the first to last position in the stored array(2) to view the list in order from the last to first position(3) to choose a specific position to view(4) to quit the application.--------using System;using static System.Console;class ArrayDemo{ static void Main() { int[] nums = {7, 6, 3, 2, 10, 8, 4, 5, 9, 1}; // Write your main here } } The image contains a C# program for managing an array and allowing user interaction through a console application. Below is the transcribed code and explanation:```csharpusing System;using static System.Console;class ArrayDemo{ static void Main() { int[] nums = {7, 6, 3, 2, 10, 8, 4, 5, 9, 1}; Console.WriteLine(" 1. to view the list in order from the first to last position in the stored array\n 2. to view the list in order from the last to first\n 3. to choose a specific position to view\n 4. to quit the application.\n"); while(true){ Console.WriteLine("Enter your choice from 1 to 4"); int c = Convert.ToInt32(Console.ReadLine()); if(c==1){ Console.WriteLine("Array from the first to last position is : "); for(int i=0;i<10;i++) Console.WriteLine(nums[i]); } else if(c==2){ Console.WriteLine("Array from the last to first position is : "); for(int i=9;i>=0;i--) Console.WriteLine(nums[i]); } else if(c==3){ Console.WriteLine("Enter array position or index to view : "); int index = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Array element at given index is : "); Console.WriteLine(nums[index]); } else if(c==4){ Environment.Exit(0); } } }}```**Program Explanation:**- **Import Libraries:** - The program uses the `System` namespace which provides essential classes and base classes for common operations. It also uses static system functionality for Console operations.- **Class Definition:** - The class `ArrayDemo` contains the `Main` method which serves as the entry point of the program.- **Array Initialization:** - An integer array `nums` is initialized with values `{7, 6, 3, 2, 10, 8, 4, 5, 9, 1}`.- **User Menu:** - The application provides a user menu with options: 1. View the array from first to last index. 2. View the array from last

We have given a C# code. We have to modify the code. The program should ask the user to choose from options 1 to 4 only till the user has not entered any sentinel value. As soon as the user enters any value other than 1,2,3, or 4, the program terminates. So the end of the last else if condition, we will add another else loop, and inside that, we will include break function to exit from the while loop.using System;using static System.Console;class ArrayDemo{ static void Main() { int[] nums = {7, 6, 3, 2, 10, 8, 4, 5, 9, 1}; Console.WriteLine("1. to view the list in order from the first to last position in the stored array\n2. to view the list in order from the last to first position.\n3. to choose a specific position to view.\n4. to quit the application."); while(true) { Console.WriteLine("Enter your choice from 1 to 4"); int c = Convert.ToInt32(Console.ReadLine()); if(c==1){ Console.WriteLine("Array from the first to last position is :"); for(int i=0;i<10;i++) Console.WriteLine(nums[i]); } else if(c==2){ Console.WriteLine("Array from last to first position is : "); for(int i=9;i>=0;i--) Console.WriteLine(nums[i]); } else if(c==3){ Console.WriteLine("Enter array position or index to view : "); int index = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Array elements at given index is : "); Console.WriteLine(nums[index]); } else if (c==4){ Environment.Exit(0); } else{ Console.WriteLine("Program terminated due to invalid input!!"); break; } } }}
