#include<stdio.h>
 
int main() {
   int arr[30], element, num, i, location;
 
   printf("\nEnter no of elements :");
   scanf("%d", &num);
 
   for (i = 0; i < num; i++) {
      scanf("%d", &arr[i]);
   }
 
   printf("\nEnter the element to be inserted :");
   scanf("%d", &element);
 
   printf("\nEnter the location");
   scanf("%d", &location);
 
   //Create space at the specified location
   for (i = num; i >= location; i--) {
      arr[i] = arr[i - 1];
   }
 
   num++;
   arr[location - 1] = element;
 
   //Print out the result of insertion
   for (i = 0; i < num; i++)
      printf("  %d", arr[i]);
 
   return (0);
}

Output:

Enter no of elements :5
1
2
3
4
5

Enter the element to be inserted :9

Enter the location2
  1  9  2  3  4  5

Explanation:

To solve this problem of the array, we just take a new element which we want to insert in the array and the location where we want to insert that element as a input. To insert that element we have to create a new space inside the array for that we shifted all the elements to its right position up to that location. which will give you a new space inside the array. now on that free position, you can easily insert that element,
