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* p = new int[n];
    int sum = 0; 
    for (int i=0; i<n; i++) {
        std::cin>> p[i];
        sum+= p[i];
    }
    int average = sum/n; 
    std::cout << average; 
    delete[] p; 

    return 0;
}
