#include <stdio.h>

void main() {
   int LA[] = {1,3,5,7,8};
   int k = 3, n = 5, item = 10;
   int i, j;

   printf(The original array elements are :\n);

   for(i = 0; i<n; i++) {

   }

   LA[k-1] = item;

   printf(The array elements after updation :\n);

   for(i = 0; i<n; i++) {
      printf(LA[%d] = %d \n, i, LA[i]);
