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 *buffer_ptr = new int[n];
    int sum = 0;

    for(int i = 0; i < n; i++)
    {
        std::cin >> buffer_ptr[i];
        sum += buffer_ptr[i];
    }

    std::cout << (sum/n) << std::endl;

    delete[] buffer_ptr;

    return 0;
}
