Unincluding 0 in integer set & determining largest/smaller integer in set?

[strangecanadian]

I am working on a small school project, i have to

Write a program that asks the user for a series of integers one at a time. When the user enters the integer 0, the program displays the following information:
-the number of integers in the series(not including 0)
-the average of the integers
-the largest integer in the series
-the smallest integer in the series
-the difference between the largest and smallest integer in the series

My problems right now are unincluding the 0 in the entered integers(so the number of integers are 3 instead of 4, and if i enter 5, 6, 7, 0 the average will be 6 instead of 4)

I also am unsure of how to determine the largest/smallest integers, my code below is what i have so far.

#include <iostream>
using namespace std;
int main()
{
    int i, avg, diff, large, small;
    int total = 0;
    int numI = 0;
    cout << "Press 0 to end the loop and display information." << endl;
    do
    {
        cout << "Please enter an integer: ";
        cin >> i;
        numI++;
        total=total+i;
    } while (i!=0);
    if (i>i)
    {
        i=large;
    }
    if (i<i)
    {
        i=small;
    }
    diff = large - small;
    total = total + i;
    avg = total / numI;
    cout << "You entered 0." << endl;
    cout << "Number of integers intered: " << numI << endl;
    cout << "Total: " << total << endl;
    cout << "Largest number: " << large << endl;
    cout << "Smallest number: " << small << endl;
    cout << "Average: " << avg << endl;
    return 0;
}

You can write the loop the following way

while ( cout << "Please enter an integer ( 0 - exit): ", cin >> i && i != 0 )
{
   numI++;
   // and so on
}

I fixed the 0 part, i just made numI=-1, but i'm having troubles with the large/small part.

You should determin maximum and minimum elements inside this loop while entering numeric values.
