#include <iostream>


using namespace std;


int main()

    int loc=3;
    int loc2=4;
    for (int i = n; i >= loc; i--) {
        arr[i] = arr[i - 1];
    }
    n++;
    arr[loc - 1] = num;
    for (int i = n; i >= loc2; i--) {
        arr[i] = arr[i - 1];
    }
    n++;
    arr[loc2 - 1] = num2;


    cout << "\nArray elements after insertion:\n";
    for (int i = 0; i < n; i++) {
        cout << arr[i] << " ";
    }
    
    cout << "\nArray elements after deletion:\n";
    
    int el=3;
