Last update on December 20 2024 12:44:00 (UTC/GMT +8 hours)

Write a C# Sharp program to read a string through the keyboard and sort it using bubble sort.

Sample Solution:-

C# Sharp Code:

using System;

// Define the exercise12 class
public class exercise12
{
    // Main method - entry point of the program
    public static void Main()
    {
        string[] arr1; // Declare an array to store strings
        string temp; // Declare a temporary string variable
        int n, i, j, l; // Declare variables for number of strings, iteration, and string length

        // Prompt the user to input the number of strings
        Console.Write("\n\nSorts the strings of an array using bubble sort :\n");
        Console.Write("-----------------------------------------------------\n");
        Console.Write("Input number of strings :");
        n = Convert.ToInt32(Console.ReadLine()); // Read the number of strings from user input
        arr1 = new string[n]; // Initialize the string array with the given number of strings
        Console.Write("Input {0} strings below :\n", n);

        // Read the strings from the user input
        for (i = 0; i < n; i++)
        {
            arr1[i] = Console.ReadLine(); // Store each string in the array
        }
        l = arr1.Length; // Get the length of the string array

        // Bubble sort algorithm to sort the array of strings
        for (i = 0; i < l; i++)
        {
            for (j = 0; j < l - 1; j++)
            {
                // Compare adjacent strings and swap them if they are in the wrong order
                if (arr1[j].CompareTo(arr1[j + 1]) > 0)
                {
                    temp = arr1[j];
                    arr1[j] = arr1[j + 1];
                    arr1[j + 1] = temp;
                }
            }
        }

        // Display the sorted array of strings
        Console.Write("\n\nAfter sorting the array appears like : \n");
        for (i = 0; i < l; i++)
        {
            Console.WriteLine(arr1[i] + " "); // Print each string in the sorted array
        }
    }
}

Sample Output:
