Write a program to insert/delete in linear array at specific position.

 

#include <stdio.h>

int main()

{

int arr[100];

int i, item, pos, size=7;

printf("Enter 7 elements: ");

// reading array

for (i = 0; i < size; i++)

scanf("%d",&arr[i]);

// print the original array

printf("Array before insertion: ");

for (i = 0; i < size; i++)

printf("%d ", arr[i]);

printf("\n");

// read element to be inserted

printf("Enter the element to be inserted: ");

scanf("%d",&item);

// read position at which element is to be inserted

printf("Enter the position at which the element is to be inserted: ");

scanf("%d",&pos);

// increase the size

size++;

// shift elements forward

for (i = size-1; i >= pos; i--)

arr[i] = arr[i - 1];

// insert item at position

arr[pos - 1] = item;

// print the updated array

printf("Array after insertion: ");

for (i = 0; i < size; i++)

printf("%d ", arr[i]);

printf("\n");

return 0;

}
