Insert an element in an Array C++

#include <iostream>     
using namespace std;
  
int main()
{ 
    int a[24],i,n,position,value;
    cout << "Enter number of elements: ";
    cin >> n;
    cout << "Enter the integer: ";
    for(i=0; i<n; i++)
    {
       cin >> a[i];
    }
    cout << "Enter the location and value of an array: ";
    cin >> position >> value;
    for (i = n - 1; i >= position - 1; i--)
    {
        a[i+1] = a[i];
    }
    a[position-1] = value;
    for(i=0; i<=n; i++)
    {
       cout << a[i] << " ";
    }
	return 0;    
}  

1. Start
2. Read the number of elements `n`.
3. Create an array `a` of size at least `n+1` to accommodate the new element.
4. Read the `n` integers and store them in the array `a`.
5. Read the values of `position` (location) and `value` (element to insert).
6. Check if the `position` is valid (i.e., `1 <= position <= n+1`).
    - If not valid, display error and stop.
7. Shift elements starting from the last element (`a[n-1]`) to the element at `position - 1`, one position to the right:
   - For `i` from `n - 1` down to `position - 1`, do:
   - `a[i + 1] = a[i]`
8. Insert the `value` at `a[position - 1]`.
9. Increment `n` by 1 to reflect the new size of the array.
10. Print the elements of the updated array from `a[0]` to `a[n-1]`.
11. End
