Dynamic Sensor Buffer

#include <iostream>

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

    if (n < 1) {
        return 0;
    }
int *sensor=new int[n];
    // Write your dynamic buffer allocation code here
   // *sensor=*sensor/n;
int sen=0;
   for(int i=0;i<n;i++)
   {
   // a=sensor[i]+a;
   // sen=a/n;
   std::cin>>sensor[i];
   sen=sen+sensor[i];

   }
   int average =sen/n;
    std::cout<<average;
    delete[] sensor;


    return 0;
}
