C#: Sort elements of the array in descending order

C# Sharp Array: Exercise-12 with Solution

Write a C# Sharp program to sort array elements in descending order.

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise12  
{  
    public static void Main() 
    {
        int[] arr1 = new int[10]; // Declare an array to store integers
        int n, i, j, tmp; // Declare variables for array size, counting, and temporary storage

        // Display a message prompting the user to input the size of the array
        Console.Write("\n\nsort elements of array in descending order :\n");
        Console.Write("----------------------------------------------\n");	

        Console.Write("Input the size of array : ");
        n = Convert.ToInt32(Console.ReadLine()); // Read the size of the array entered by the user

        // Prompt the user to input 'n' elements in the array
        Console.Write("Input {0} elements in the array :\n", n);
        for (i = 0; i < n; i++)
        {
            Console.Write("element - {0} : ", i);
            arr1[i] = Convert.ToInt32(Console.ReadLine()); // Store user input in the array
        }

        // Sort the elements of the array in descending order using nested loops and swapping if needed
        for (i = 0; i < n; i++)
        {
            for (j = i + 1; j < n; j++)
            {
                if (arr1[i] < arr1[j]) // Compare elements to arrange them in descending order
                {
                    tmp = arr1[i]; // Swap elements if the condition is met
                    arr1[i] = arr1[j];
                    arr1[j] = tmp;
                }
            }
        }

        // Display the sorted elements of the array in descending order
        Console.Write("\nElements of the array in sorted descending order:\n");
        for (i = 0; i < n; i++)
        {
            Console.Write("{0}  ", arr1[i]); // Print sorted elements
        }
        Console.Write("\n\n"); // Print a new line for formatting
    }
}

Sample Output:

sort elements of array in descending order :                                                                  
----------------------------------------------                                                                
Input the size of array : 3                                                                                   
Input 3 elements in the array :                                                                               
element - 0 : 2                                                                                               
element - 1 : 5                                                                                               
element - 2 : 0                                                                                               
Elements of the array in sorted descending order:
