Answer 1

#include <iostream>
using namespace std;
int main()
{
    int n = 0, sum = 0;
    double av = 0;
    do
    {
        cout << "Enter n = ";
        cin >> n;
    }
    while (n <= 0);
    for (int i = 1; i <= n; i++)
    {
        sum += i;
    }
    av = double(sum) / n;
    cout << "Average = " << av;
    cin.ignore(256, '\n');
    cin.get();
}
