max/min in a list of numbers

[shockalaca]

I am having trouble finding the min and max in a list. I set up a run function so that it does not repalce the number with the next number in the list. Here is what I have and it will compile but the min and max use the number -999.

#include <stdio.h>
int factorial (int number);
int main ()
{
        int count = 0, run = 1;
        double number, sum, average, min, max;
        sum = 0;
        printf ("Please enter the numbers. Enter -999 when done.\n");
        while (number != -999)
        {
         scanf ("%lf", &number);
         if (number != -999)
         {
          sum += number;
          count++;
          }
        }
        if (count != 0)
         {
         average = sum/count;
         if (run == 1) {
max=number;
min=number;

run=0;
}
if (number<min)
min=number;
if (number>max)
max=number;
count += 1;

         printf ("The sum of the given list of number is %f.\n", sum);
         printf ("The average of the given list of numbers is %f.\n", average);
         printf ("The maximum number in the list is %f.\n", max);
