Write a C# Sharp program to sort a string array in ascending order.

Sample Solution:-

C# Sharp Code:

using System;  

// Define the Exercise11 class
public class Exercise11  
{  
    // Main method - entry point of the program
    public static void Main() 
    {
        string str; // Declare a string variable to hold user input
        char[] arr1; // Declare a character array
        char ch; // Declare a character variable
        int i, j, l; // Declare variables for iteration and string length

        // Prompt the user to input a string
        Console.Write("\n\nSort a string array in ascending order :\n");
        Console.Write("--------------------------------------------\n");  
        Console.Write("Input the string : ");
        str = Console.ReadLine();	// Read the input string from the user
        l = str.Length; // Get the length of the input string
        arr1 = str.ToCharArray(0, l); // Convert the input string to a character array

        // Perform bubble sort to sort the character array in ascending order
        for (i = 1; i < l; i++)
        {
            for (j = 0; j < l - i; j++)
            {
                // Compare adjacent characters and swap them if they are in the wrong order
                if (arr1[j] > arr1[j + 1])
                {
                    ch = arr1[j];
                    arr1[j] = arr1[j + 1];
                    arr1[j + 1] = ch;
                }
            }
        }

        // Display the sorted string
        Console.Write("After sorting the string appears like : \n");
        foreach (char c in arr1)
        { 
            ch = c;
            Console.Write("{0} ", ch); // Print each character of the sorted array
        }
        Console.WriteLine("\n");
    }
}

Sample Output:

Sort a string array in ascending order :                                                                      
--------------------------------------------                                                                  
Input the string : w3resource                                                                                 
After sorting the string appears like :
