Dynamic Sensor Buffer

#include <iostream>

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

    if (n < 1) {
        return 0;
    }

    int* array_1 = new int[n];

    int average = 0;

    for (int i = 0; i < n; i++) {
        std::cin >> array_1[i];
        average += array_1[i];
    }

    average /= n;

    std::cout << average;

    delete[] array_1;

    array_1 = nullptr;

    return 0;
}
