Last update on December 20 2024 12:36:26 (UTC/GMT +8 hours)

Write a C# Sharp program to insert another value in the array (unsorted list).

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise14  
{  
    public static void Main() 
    {
        int[] arr1 = new int[10]; // Declare an array to store integers
        int i, n, p, x; // Declare variables for array size, counting, position, and new value

        // Display a message prompting the user to input the size of the array
        Console.Write("\n\nInsert New value in the unsorted 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("Input the value to be inserted : ");
        x = Convert.ToInt32(Console.ReadLine()); // Read the value to be inserted
        Console.Write("Input the Position, where the value to be inserted :");
        p = Convert.ToInt32(Console.ReadLine()); // Read the position where the value will be inserted

        Console.Write("The current list of the array :\n");
        for (i = 0; i < n; i++)
            Console.Write("{0} ", arr1[i]); // Display the existing array

        /* Move all data at the right side of the array */
        for (i = n; i >= p; i--)
            arr1[i] = arr1[i - 1]; // Shift elements to make space for the new value

        /* Insert the value at the given position */
        arr1[p - 1] = x;

        Console.Write("\n\nAfter Insert the element, the new list is :\n");
        for (i = 0; i <= n; i++)
            Console.Write("{0} ", arr1[i]); // Display the updated array with the inserted value

        Console.Write("\n\n");
    }
}

Sample Output:

Insert New value in the unsorted array :                                                                      
-----------------------------------------                                                                     
Input the size of array : 2                                                                                   
Input 2 elements in the array in ascending order:                                                             
element - 0 : 5                                                                                               
element - 1 : 15                                                                                              
Input the value to be inserted : 10                                                                           
Input the Position, where the value to be inserted :2                                                         
The current list of the array :

After Insert the element the new list is :
