Last update on December 20 2024 12:36:27 (UTC/GMT +8 hours)

Write a C# Sharp program to delete an element at the desired position from an array.

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise15  
{  
    public static void Main() 
    {
        int i, pos, n; // Declare variables for counting, position, and array size
        int[] arr1 = new int[50]; // Declare an array to store integers

        // Display a message prompting the user to input the size of the array
        Console.Write("\n\nDelete an element at desired position from an array :\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

        /* Store values into the array */
        Console.Write("Input {0} elements in the array in ascending order:\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
        }

        Console.Write("\nInput the position where to delete: ");
        pos = Convert.ToInt32(Console.ReadLine()); // Read the position of the element to be deleted

        /* Locate the position in the array */
        i = 0;
        while (i != pos - 1)
            i++; // Find the index position that needs to be deleted

        /* Replace the element at the position with its right neighbor */
        while (i < n)
        {
            arr1[i] = arr1[i + 1]; // Shift elements to the left to overwrite the element to be deleted
            i++;
        }
        n--; // Decrease the size of the array by one after deletion

        Console.Write("\nThe new list is : "); 
        for (i = 0; i < n; i++)
        {
            Console.Write("  {0}", arr1[i]); // Display the updated array after deletion
        }  
        Console.Write("\n\n");
    }
}

Sample Output:

Delete an element at desired position from an array :                                                         
---------------------------------------------------------                                                     
Input the size of array : 3                                                                                   
Input 3 elements in the array in ascending order:                                                             
element - 0 : 2                                                                                               
element - 1 : 4                                                                                               
element - 2 : 6  
Input the position where to delete: 2      
The new list is :   2  6
