Dynamic Sensor Buffer

#include <iostream>

int main() {
    int n;
    std::cin >> n;

    if (n < 1) {
        return 0;
    }

    // Write your dynamic buffer allocation code here
    int *ptr = new int[n];
    for(int i = 0; i < n; i++)
    {
        std::cin >> *(ptr+i);
    }

    int val = 0;
    for(int i = 0; i < n; i++)
    {
        val += *(ptr+i);
    }
    val /= n;

    std::cout << val;

    delete[] ptr;


    return 0;
}
