Hi all,

///Program for new element to be added in array

int[] arr1 = new int[] {2,3,4,5,6};

int m, n;

Console.Write("Input the value to be inserted in array:");

m = Convert.ToInt32(Console.ReadLine());

Console.Write("Input the position,where the value to be inserted in array:");

n = Convert.ToInt32(Console.ReadLine());

/* Move all data at right side of the array */

for (int i = arr1.Length; i >= n; i--)

arr1[i] = arr1[i -1];

/* insert value at given position */

arr1[n - 1] = m;

Console.Write("New array is:");

for(int i =0;i

{

Console.Write("{0} ", arr1[i]);

}

Console.ReadLine();

///********************************************

Can someone help me for this program.Its showing me error on arr1[i] = arr1[i -1] ; "index was outside the bounds of array."how can i solve it.pls help.

Thanks

Hi

array index is always less than the length of array

in your case array length is 5 and array index i
arr1[0] =2
arr1[1] =3
arr1[2] =4
arr1[3] =5
arr1[4] =6

so you can not insert element fifth index ie arr1[5]
if you try this arr1[5] =7 it will through exception

try this

int[] arr1 = new int[] {2,3,4,5,6};
int m, n;
Console.Write("Input the value to be inserted in array:");
m = Convert.ToInt32(Console.ReadLine());
Console.Write("Input the position,where the value to be inserted in array:");
n = Convert.ToInt32(Console.ReadLine());
/* Move all data at right side of the array */
for (int i = arr1.Length-1; i >= n; i--) // if you use arr1.Length ie 5 in next line arr1[5] through exception because you are trying to insert the value at index 5 but your array having only 0 to 4 index
arr1[i] = arr1[i -1]; //
/* insert value at given position */
arr1[n - 1] = m;
Console.Write("New array is:");
for(int i =0;i
{
Console.Write("{0} ", arr1[i]);
}
Console.ReadLine();

Hi,

Please try below code -

int[] arr1 = new int[] { 2, 3, 4, 5, 6 };
int m, n;
Console.Write("Input the value to be inserted in array:");
m = Convert.ToInt32(Console.ReadLine());
Console.Write("Input the position,where the value to be inserted in array:");
n = Convert.ToInt32(Console.ReadLine());
int[] arr2 = new int[arr1.Length + 1];
arr1.CopyTo(arr2, 0);
/* Move all data at right side of the array */
for (int i = arr2.Length - 1; i >= n; i--)
arr2[i] = arr2[i - 1];
/* insert value at given position */
arr2[n - 1] = m;
arr1 = arr2;
Console.Write("New array is:");
for (int i = 0; i < arr1.Length; i++)
{
Console.Write("{0} ", arr1[i]);
}
