Question

For the following C# program: 
Let’s add one more user defined method to the
program. This method, called ReverseDump is to output the values in the array in revere order
(please note that you are NOT to use the Array.Reverse method from the Array class). The
approach is quite simple: your ReverseDump method will look very similar to the Dump method
with the exception that the for loop will count backwards from num 1 to 0 . The method header
will look like:

public static void ReverseDump(int [] arrItems, int num)

***What needs to be done***
Create the ReverseDump method and Call the ReverseDump method in main
The goal is just to output the values from the array in reverse order.


****Program in C#****
using System;
public static class Lab4_1
{
   public static void Main()
   {
       int[] dataArray = new int[10] {9, 8, 7, 6, 5, 4, 3, 2, 1, 0};
       int n = 0;

       // Fill the array
       Fill(dataArray, ref n);
      
       // Display the array contents
       Dump(dataArray, n);
      
       // Pause until user is done
       Console.ReadLine();
   }
             
   // Method:       Fill
   // Description:  Fill an array with values.
   // Parameters:   arrValues: the array to fill.
   //               num: number of elements in the array.
   // Returns:      void
   public static void Fill(int[] arrValues, ref int num)
   {
      // input the number of data values to put in the array
      do
      {           
          Console.Write("Enter the number of elements (between 0 and 10) => ");
          num = Convert.ToInt32(Console.ReadLine());
      } while(num < 0 || num > 10);
             
      // loop to enter the values
      for(int i = 0; i < num; ++i)
      {
         Console.Write("Enter the Element {0} => ", i);
         arrValues[i] = Convert.ToInt32(Console.ReadLine());
      }
   }
        
   // Method:       Dump
   // Description:  Display the contents of an array.
   // Parameters:   arrVals: array to be displayed.
   //               num: number of elements in the array.
   // Returns:      void
   public static void Dump(int[] arrVals, int num)
   {
      // output the values from the array
      Console.WriteLine("The elements in the array are:");
      for (int i = 0; i < num; ++i)
         Console.WriteLine(" {0}", arrVals[i]);
   }
}

SOURCE CODE IN C#:

using System;

public static class main

{

public static void Main()

{

int[] dataArray = new int[10] {9, 8, 7, 6, 5, 4, 3, 2, 1, 0};

int n = 0;

// Fill the array Fill(dataArray, ref n);

Fill(dataArray, ref n);

Dump(dataArray, n);

ReverseDump(dataArray, n);

}

// Method: Fill

// Description: Fill an array with values.

// Parameters: arrValues: the array to fill.

// num: number of elements in the array.

// Returns: void

public static void Fill(int[] arrValues, ref int num)

{

// input the number of data values to put in the array

do

{

Console.Write("Enter the number of elements (between 0 and 10) => ");

num = Convert.ToInt32(Console.ReadLine());

}while(num < 0 || num > 10);

// loop to enter the values

for(int i = 0; i < num; ++i)

{

Console.Write("Enter the Element {0} => ", i);

arrValues[i] = Convert.ToInt32(Console.ReadLine());

}

}

// Method: Dump

// Description: Display the contents of an array.

// Parameters: arrVals: array to be displayed.

// num: number of elements in the array.

// Returns: void

public static void Dump(int[] arrVals, int num)

{

// output the values from the array

Console.WriteLine("The elements in the array are:"); for (int i = 0; i < num; ++i)

Console.WriteLine("{0}", arrVals[i]);

}

// Method: ReverseDump

// Description: Display the contents of an array in reverse order.

// Parameters: arrItems: array to be displayed.

// num: number of elements in the array.

// Returns: void

public static void ReverseDump(int [] arrItems, int num)

{

//output the values from the array in reverse order

Console.WriteLine("The elements in the array in reverse order are:"); for (int i = num-1; i >= 0; --i)

Console.WriteLine("{0}", arrItems[i]);

}

}

OUTPUT:

Enter the number of elements (between 0 and 10) => 5 Enter the Element 0 => 1 Enter the Element 1 => 2 Enter the Element 2 => 3 Enter the Element 3 => 4 Enter the Element 4 => 5 The elements in the array are: 3 The elements in the array in reverse order are: کر لیا

Enter the number of elements (between 0 and 10) => 5 Enter the Element 0 => 1 Enter the Element 1 => 2 Enter the Element 2 => 3 Enter the Element 3 => 4 Enter the Element 4 => 5 The elements in the array are: 3 The elements in the array in reverse order are: کر لیا
