Solution :

#include<iostream>
#include <iomanip>
using namespace std;

int main() {
  
   double sum;
   double number;
   int n;
  
   cout << "Enter the upper limit: ";
   cin >> n;
   cout << "Enter " << n << " numbers: " << endl << endl;
   int i = n;
  
   do {
       cout << "Enter a number: ";
       cin >> number;
       sum += (double)number;
       n--;
   } while(n > 0);
  
   double avg = sum/i;
  
   cout << fixed << setprecision(2);
   cout << "The sum of all numbers from 0 to " << i << " equals " << sum << "." << endl;
   cout << "The average equals " << avg << ".";
   return 0;
}
