problem with my array help please

[ace55]

I'm having difficulty implementing the mean/median/max/min.
I get the fact that the first in my sorted would be the min, but how would i get the max if its based on user control so i don't know what the last one is?

#include <iostream>

using namespace std;

void sort (double x[], int length)
{

    bool continueSort = true;
    int i;
    double temp;
    while (continueSort == true)
    {
        continueSort = false;

        for (i=0;i< length-1; i++)
        {
            if (x[i] > x [i+1])
            {
                temp = x [i];
                x[i] = x[i+1];
                x[i+1] = temp;
                continueSort = true;
            }
        }
    }

}

int main()
{
    int i,scoreCount,sum=0;
    double mean, median, min, max;
    cout << "Enter Score Count <1-20> ";
    cin >> scoreCount;
    if (scoreCount >= 1 && scoreCount <= 20)
    {
        double x[scoreCount];
        for (i=0;i<scoreCount;i++)
        {
            cout << "Enter Score #" << i + 1 << ": ";
            cin >> x[i];
            sum = sum + x[i];

        }
        cout << "Original Data: "<< endl;
        for (i=0;i<scoreCount;i++)
        {
            cout << x[i] << " ";
        }
        cout << endl;

        sort( x, scoreCount);
        cout << "Sorted Data: " << endl;
        for (i=0;i<scoreCount;i++)
        {
            cout << x[i] << " " ;
        }
        min = x[0];
        max = x[?]
        mean = sum/scoreCount;
        cout << "Min Value: " << min << endl;
        cout << "Max Value: " << max << endl;
        cout << "Mean: "      << mean << endl;
        cout << "Median: "    << median << endl;


    }
    else
    {
        cout << "Class size is NOT within required range. The required range is 1 to 20." << endl;
    }
    return 0;

max:
x[?] => x[scoreCount - 1]

median:

#include <cmath>
/*...*/
int middle = scorecount / 2;
median = (scoreCount%2) ? x[middle] : ((x[middle] + x[middle+1]) / 2);

cin >> scoreCount;
double x[scoreCount];

This is not standard C++ and should not work. I recommend to turn off your compiler extension which allows this.
