#include <iostream>

using namespace std;

void main(void){

setlocale(LC_ALL, "rus");

int n,i,sum=0,r;

cout << "Enter number pls";

cin >> n;

int *arr = new int[n];

for (i = 0; i < n; i++){

 cout << "Pls enter" << " " << i << " " << "element";

 cin >> arr[i];

}

for (i = 0; i < n; i++){

 sum = sum + arr[i];

}

delete[] arr;

r = sum / n;

cout << "Среднее равно"<< " " << r;
